Can't enter Bios with Del key

Hello, I have a RockPi4-SE running Debian. I am attempting to run Windows from a bootable USB drive I created through the WIKI page, however, I can not enter bios to change the boot override to USB. Pressing the delete key does not circumvent the loading of the Debian OS from my SD card. Always goes to Debian, and if i remove the SD card nothing happens at all. How can I enter the Bios page other than using Del Key? Should I flash a new BIOS? Is there a BIOS reset or means to force booting from USB? Thank You
