Describe the bug
I am setting up a node with fixed public IP + port. When manually set address:port, the UDP port get later replaced by the ENR auto update.

I have manually added this patch below in my node fork and seems to work properly for my use case. But maybe this could break other things. I would like to open a PR with a patch if this is the correct approach to solve that.
if discv5_addr.is_some() || discv5_addr_ipv6.is_some() || self.disable_nat {
builder.disable_enr_update();
}Steps to reproduce
Start op-reth with given params:
--discovery.v5.port=30303
--discovery.v5.addr=34.159.243.134
--disable-nat
--disable-discv4-discovery
