Does the system also freeze on lock screen without the sleep? superkey(winkey)+L

I’m no expert on TuxedoOS you might need to contact their support https://www.tuxedocomputers.com/en/Help-Support.tuxedo I also found this while digging. https://www.reddit.com/r/tuxedocomputers/comments/17ai79z/how_to_enable_hibernation_in_tuxedo_os_encrypted/

In the sense of windows boots and changes values of the bios that aren’t saved between boots. Similar to how fan curves can be changed or GPUs overclocked.

I don’t know enough to rule out that windows could overwrite bios.

You could try a tool like LACT and setting your gpu power profile to always highest. Another thing you could check is your BIOS settings, https://www.tomshardware.com/reviews/bios-beginners,1126-8.html or checking if the latest bios is installed https://red.artemislena.eu/r/gigabyte/comments/1b3bffy/gigabye_b650_aorus_elite_ax_rev_10_sleeppower/
