Ability to disable NAT for IPv6 GUA

Good day,
So I'm in a pretty weird situation right now. I created a bridge network in Podman with a GUA /56 subnet hoping to give each container a publicly available address. However, I have no way of instructing Podman to disable NAT for this specific bridge network. My current stop gap workaround is to just prepend a `RETURN` rule for all the subnet in the NAT chain as so `ip6tables -t nat -I POSTROUTING -s XXXX:YYYY:ZZZZ:000::/56 -j RETURN`

I want to do this in a clean way without having to wrangle iptables. How feasible is this?
