How to notify openvpn clients to renegotiate connection if a setting changed on the openvpn server interface?

General questions

Hello.
I’m using openvpn for a management connection to my various routers that i manage. Everything works great until i want to make a change to the openvpn config itself. At that point as soon as i hit enter on the commit command my connection to the router will drop.
If i tell the openvpn client to reconnect everything starts working again. So i have a few questions. Is there a way for the server to tell the client to renegotiate the connection? Or better yet, would there be a way to keep the session across an interface reload?
The connections only drop if you make a change on the interface it’s using so if i connect on vtun0 and make a change on vtun1 i can commit fine without having to reconnect.
Here is my config for vtun0 which is the management interface.

vyos@vyos-sh# show
 encryption {
     cipher aes256
 }
 mode server
 openvpn-option "verb 5"
 persistent-tunnel
 protocol udp
 server {
     client 1 {
     }
     client 2 {
     }
     name-server 10.50.50.xx
     name-server 10.50.50.xx
     push-route 10.50.xx.xx/24
     push-route 10.2.xx.x/24
     push-route 10.33.xx.x/24
     push-route 10.0.xx.x/29
     push-route 10.33.xx.x/24
     push-route 10.4.xx.x/24
     subnet 10.50.xx.x/24
 }
 tls {
     ca-cert-file /config/auth/openvpn/ca.crt
     cert-file /config/auth/openvpn/cert.crt
     dh-file /config/auth/openvpn/dh2048.pem
     key-file /config/auth/openvpn/privatekey
 }

Anyone have any thoughts or faced something similar?
