As someone who switched to Linux, and found reasons not to for literal decades, this has helped me:

Have a second ssd in your PC that is untarnished by the windows bootloader.

This way one can easily switch via BIOS / UEFI and no other annoying software.

Dual booting is also less annoying, if you switch via boot menu. It lets you test drive and configure Linux anytime you’re in the headspace for it and reduces pressure on yourself.

Install linux on it. My current favorite for your situation would be Fedora KDE Plasma Desktop Spin (what a mouthful). Have another exfat partitioned usb disk ready for file exchange with windows. Again, this makes handling windows easier, has nothing to do with linux.

Nvidia on fedora works good enough. third party repos also help a lot.

streamdeck is wonderful hardware, I know a friend who uses it daily with streamdeck_ui

• same with GoXLR Configuration Utility. Software is there, the only question is does it work for you.

This is to my knowledge as close to “official” as you can get. Good luck on your journey!

Can we please stop calling reactionary right wing extremists “conservative”. There is nothing these people want to conserve.
