how can i make my microphone mono? UR12

Guys i bought UR12, and like all users who buy this product, i have one xlr microphone and 1 electric guitar.

proglem is i plug my xlr mic and in games or some applications people hear me only from left channel. i have to make this mono but all grayed out from windows menu.

and the yamaha application doesnt have any channel settings, pls this option is available for focusrite users, dont make me regretful not to buy focus rite ):
