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.

It never did so in updates for me, but assuming it did, UEFI stuff is fixable, just mess with the settings for five seconds :P
