Persistent MTU setting of Wireguard interface

Hello, how can I set a persistent MTU for a Wireguard client connection?

The following works but doesn’t survive reboots:

ip link set wg0 mtu 1320

Is there an option for this in /etc/config/wireguard?

Hello, yes.

uci set wireguard.wg_peer_5093.mtu=1320
uci commit wireguard
