UEFI is already supported.

Is this the latest Guix version (1.1.0)?  What kind of machine did 
you try it on, and which error (if any) did you get?  Does the 
same installer boot and run fine when booted in CSM (‘legacy’) 
mode?  Could you try a different model of USB drive (this once 
‘solved’ it for me)?

Kind regards,
