Don't own this amp myself, but friend does. We had it open for rebiasing and he showed me the small jumper to make them monoblocks. It's right in the center when you open them up. It's a wee-tiny little jumper that's probably sitting across one pin, leaving others exposed. It should be covering all pins to convert to a monoblock.

HOWEVER - BEFORE YOU TRY THIS - please talk to a dealer or to the manufacturer directly. Again, I don't own this amp and am working from memory.
