BIOS settings, how to find 'Power on by PS/2 keyboard'

I`ve got Chuwi Corebook Xpro i3 1215 at about four moths ago, at the begging of using this device i was solving the issue related with fan noise. I’ve done point-stated tuning in thermal configuration of Bios, so now i faced with automatically coming out of sleep mode, when lid is closed. As i noticed it caused by screen’s touching the keyboard with closed lid what caused Notebook turning on. How can i find option named “Power on by PS/2 Keyboard” or something similar in my BIOS??
BIOS version AMI 5.26
