Bios in windows

i have a 2020 intel based macbook pro and I have installed windows 10 pro on it. i want to change something in the BIOS but I cannot go into it.

is it cause since windows isn't the default OS then you cant enter the BIOS?

is it that there is a special way to enter the bios when ur doing it from a MacBook?

does this make sense?

any help would be great!!
