I run two Windows machines - both currently on 10.
Thankfully, one cannot run 11 (the other could) and I really get tired using two different versions at the same time. Hence, Microsoft have made it quite clear I need to remain on 10. Indefinitely.
Then permanently wander off to MacOS and/or a flavour of Linux. (Already have an M1 Mac mini and a Linux box. So neither is unfamiliar.)
Ironically, I do have 11 running - in Parallels under MacOS. But will probably scrap that when my trial comes to an end. The only way I would keep it is if Microsoft offer an ARM licence for 11.
