That is true for me now, but for years I used dual boot on old BIOS based systems so idk /shrug

That’s actually more safe. Windows can rewrite the UEFI setting to make itself the default again (although that’s of course easy to fix). But it can’t change your BIOS boot order.

When I booted into Windows 8.1 on my 2016 desktop computer, it immediately destroyed my boot loader for Ubuntu making it impossible to boot. I can’t confirm if it was BIOS or UEFI though. I had to use a convoluted technique to restore the boot loader for it to load Ubuntu afterwards each time I ran Windows.
