The entire lower dash panel and that switch panel are just held in with tension clips. Start at the bottom and begin pulling with steady/firm force with maybe a little occasional oompf thrown in. Work your way around the edges and up to that panel. Switch blanks normally just have little hooks you can disengage from behind.
Note, if you have the accessory ambient lights you’ll need to unplug the housing from the wiring harness to get the panel out of the way. Also will need to unplug the dash lighting dial at the top.
