Is there a way to decrease the "dead peer detection timeout" values from 300 seconds?

openconnect has this:

       --force-dpd=INTERVAL
              Use INTERVAL as Dead Peer Detection interval (in seconds). This will cause the client to use DPD at the specified interval even if the server hasn't requested it, or at a dif‐
              ferent interval from the one requested by the server.

              DPD  mechanisms vary by protocol and by transport (TLS or DTLS/ESP), but are all functionally similar: they enable either the VPN client or the VPN server to transmit a signal
              to the peer, requesting an immediate reply which can be used to confirm that the link between the two peers is still working.

I haven't had any success with gpclient to accept this.

Yes, I can support this. Which client do you use, the CLI or the GUI?

I use cli

Added the --force-dpd option in 2.4.5.
