Because that's how the laptop came when I bought it.

Hi again

Then i understand why.

If you ever plan on a clean install, so strongly consider undo the Raid. You will have more options with two disks then two disks as one. Its easier to make a disk image on one then on a Raid array. Raid 0 is sensitive as if one disk fails all data is lost if you dont have a external backup.
Raid 0 is really good if you need high write/read speed and is often used in some servers that handles a lot of raw data 24/7
Raid 1 then the second disk becomes a mirror of the first one.. so if one die, the system keeps on going. Downside, you lose half of the data storage space as one disk is just a mirror of the first one.
So next time you considering a clean install.. keep this in mind.
Not doable. I do have plenty of programs to reinstall. I am not looking to create a dual boot system. I was only looking to maximize privacy.
Dualboot system is the best way to privacy. It is totally doable to run Linux inside windows WSL Windows subsystem for Linux.. But this will become useless in privacy when Microsoft kickstart the Windows Recall.. Then its game over.
If you feel uncomfortable with messing with your Raid setup and wants to get the best of both worlds.. Then you can get an external USB SSD/M.2 disk that someone else mention instead of using USB sticks. Way-way-way better performance and longer lifespan as a USB stick will fail after to many writes compare to a SSD/M.2 disk.
One thing that Linux can that windows cant, is to install the operating system on an external harddrive.

so you can get a dual boot system without messing with your current setup.
I have never used Linux, however TAILS is Linux based. I chose TAILS purely after it had been recommended in
this video. Right now, I get the feeling I'm chasing rainbows.
I started with Linux in 2018 and i had never-ever even touched a computer with Linux before, so i can relate to what you feeling when it dont working out of the box as you want it too.

As for Tails.. i would not recommend that for "stage 1" of privacy. And about now you wonder... stage1?

I have been in the Privacy track since 1995.. the right to be anonymous online, so i have set it to 3 levels of privacy.
Stage1. is when you only want hide from Big tech to have the right to chose to who you share your data with.
This mean a OS that isn't collecting data about you, a web browser that isn't sending your userdata to big-tech (Chrome and edge is the evil ones)
And about here will some MS fanboy/girl will say something about edge and win dont collecting data... I just say dont,... start a separate thread if you want to have that discussion. 
Stage2. you are a whistleblower or a journalist working around the world so you need to be able to have isolated communication that dont leave any traces.
Stage3. you are a real target with top secret work that governments around the world or criminal hackers want to target you as an individual, so you have to be able to be totally invisible and cant be traced by anyone, not even the NSA or other powerful entities or the worlds best hackers.
This last one is less then 0.5% of the worlds population and this stage for a normal person is just tinfoil hat warning.
With running Linux on an external drive with a VPN and two or three web browsers will leave you at stage 1.5.
Tails is more stage2 and is probibly overkill for you and will only create uncomfortable-ness for you.
As you have Nvidia i would recommend Pop_OS with Nvidia support
Download Pop!_OS by System76
Look for the ISO ( Pop!_OS 22.04 LTS with NVIDIA )
Most all Linux versions can be run from an USB-stick without installing it... So make an USB stick with this one and try if that one will play a bit nicer with your computer
As for the step to actually install Pop_OS on an external harddrive to really use for years to come.. We can take that step then when you see it works.
I might have missed something.. I haven't woken up yet as I'm still drinking my morning coffee. *LOL*
