In the rear of the desk, there are two support blocks that can support a mount as well as anywhere that is the full thickness of the desk - do not put a mount on the thin 9mm top and bottom plywood sheets.
The top to bottom thickness of the desk is 2.62"
TLDR - The mitigating factor is if a mount can reach 2.62” or the thickness of the desk.
