My friend bought one of those, paired with I think 64gb of EMMC storage which is basically an SD card. It couldn’t browse the internet really with Edge in it’s default settings. I had to disable so much crap but I got it usable with Firefox.

You can’t put Linux on an Xbox One Series X. The security system prevents running unsigned code and the bootloader will only boot the Xbox operating system. There has never been an exploit found for the Xbox One Series X or S for unlocking the bootloader.
