Not on W11. I have a virtual machine with W11. I double booted to a 
Linux CD to force delete some file, and for that I had to disable secure 
boot. Subsequently I booted Windows, to find that network was gone. So I 
had to reboot and enable back secure boot.

So people double booting need secure booting enabled.
