unbound bind to localhost

[securid]

Hi, I am moving my pfsense over to OPNsense.

I am using another primary DNS service, which listens on LAN on 53 and forwards internal domain queries to 127.0.0.1:5353.

I can configure unbound on 5353, but I can only select my LAN or WAN interfaces, I cannot select (as with pfsense) localhost. Screenshot should make clear what I mean. pfsense then does not listen on other interfaces.

In OPNsense, when I select LAN, it listens on both the LAN and localhost, but I would really prefer it does not listen on LAN as well.

Any chance I can set this the same in OPNsense?

Thanks!
