X1 Carbon 5th - BIOS 1.22 removes Panel Self-Refresh Option

I updated the BIOS of my X1C5 to 1.22 today and realized that this removed the "Panel Self-Refresh" option in the Intel Graphics power settings. I guess it's related to the fix mentioned in the readme "Fixed an issue where WQHD LCD panel might have flicker.", i.e. they probably just disabled this function via BIOS. I however have a FHD display and haven't noticed any flickering since day 1. Since this option is supposed to save battery power I would appreciate if it could be enabled again at least for FHD displays. I downgraded to 1.20 and the option is back in the Intel settings.
