|It's the only place you can do anything about it, but I think most machines have a minimum of one pass.|
Here's two examples from quite different motherboards (my previous and present ones):
BIOS Features Setup - "Quick Power on self test" (set to Enabled). This limits it to one pass instead of three.
Boot Setup Menu - "Quick Boot Mode" (set to Enabled). This skips the memory test retest.
You obviously need to check the info on your own particular motherboard (if you haven't already).
