First time posting so be gentle

So I'm currently looking to build a ZNC bouncer on an old Raspberry Pi which I have laying around. I'm wanting it to sit behind a VPN which I have no issue with configuring however I'm wanting to know whether it's possible to have a script which has a set list of VPN connections for instance au151.nordvpn.com.tcp443.ovpn, au152.nordvpn.com.tcp443.ovpn, au153.nordvpn.com.tcp443.ovpn that it cycles each time the device is restarted? I'm not wanting to rely on one specific connection incase it goes down or something.
Any help and advice would be greatly appreciated.
