I need to change the ZF flag in EFLAGS conditionally after checking few variables. is there a way to do it

Code:
if (EIP == OFFSETS.CMPJUMP) then
      if (EDX == 0x6AC2C0 and (e110 == 0)) then
                    --how can I change ZF flag to 1 here?
      end
end


thanks in advance

I don't like to use Lua to write assembly code, so I'm not sure.... but I think maybe "EFLAGS" is an exported variable. It's probably just a bitmask (SF|ZF||AF||PF||CF). So, I'd try toggling the ZF bit.
