is there a way to hard set MTU value on WG0 interface from 1420 to 1500?

Hello
I have setup a Pfsense site to site VPN that routes all traffic ( 0.0.0.0/0) from site A to site B and it works as I need to but at first I could not figure out why google services and its apps did not worked correctly so some websites and apple email servers stoped responding or worked halfway and after some time searching about it I find out that someone else had a similar problem with Wireguard (google services did not worked inside its tunnel and it was due to MTU from interface WG0 was set to low (so it was mine inside pfsense as the default value is set to 1420) I change the MTU value to 1500 and all started to worked fine (google, youtube, apple email servers and those other websites)
Now my question: after changing the MTU value to 1500 of the WG0 interface (image 2) and validating that the MTU values is set (image 3) after some time the MTU values will revert back to 1420 - Is there a way to hard set the MTU values from 1420 to 1500?Image 1 shows what happens to google services when MTU value is set to 1420 on WG0

@elguapo Try clamping the MSS to 1420 and leave the MTU as default (1420)
