How to gracefully reboot a Juniper spine with evpn

Hey guys, We’ve got a juniper leaf/spine switching environment with vxlan & evpn. Now we have to perform firmware upgrades with reboots and we currently don’t have a way to gracefully reboot a spine without losing packets. I’m thinking about changing bgp prios before disabling the network interfaces but maybe one of you guys have a better way to reboot a spine. I didn’t find any best practice for this and rebooting a spine without any preparation causes a big connection drop in the network.
