This really depends on your grub version and distribution.
Historically grub did not have any way to interrupt boot

Yes, you can check the environment variable $grub_platform. It is "pc"
for legacy BIOS and "efi" for UEFI.

No, it is not implemented.

No. "menuentry" is a command which creates menu entry. Commands inside
this menu entry are executed when you select it, at which point it is
too late.

Well, (,gpt2) means "the second partition on the disk grub was loaded

native drivers on UEFI (actually I am pretty sure it won't).
nativedisk drivers were never intended for BIOS/UEFI systems.
