Put to sleep with power button on desktop PC - possible?

I'd like to use the power button on the case of my desktop PC as a sleep/wake button on my Big Sur OpenCore Intel Hackintosh. Is this possible? Right now I have to click Apple-Sleep or use another software way, which is a bit annoying in situations where the display is off (takes a few seconds to wake). BS 11.4 with OC 0.7.0, Asus Prime Z490-P mobo.

Thanks.
