Accessing Peplink network from remote site (VPN/PepVPN?)

I have two sites:

Site 1
192.168.201.x

Site 2
192.168.202.x

Both running Peplink hardware.

Both sites are behind additional firewalls, but PepVPN working on both, however I need site 2 to be able to access the devices on the LAN of site 1. I can’t set site 2 to 192.168.201.x as it causes a “Route Conflict”

Is this possible?

I have no devices on the 192.168.202.x network so this site/config can be changed if needed.

Thank you

Does either site 1 or site 2 have a static IP?
