Signing key not found error

All;

I am trying to setup a few AWS EC2 nodes for a client, they passed me 
EC2 VMs with RHEL 10

I ran this which was successful:
sudo dnf install -y 
https://download.postgresql.org/pub/repos/yum/reporpms/EL-10-x86_64/pgdg-redhat-repo-latest.noarch.rpm


However when I run this command:

sudo dnf -qy module disable postgresql


I get:
Error: Failed to download metadata for repo 'pgdg-common': repomd.xml 
GPG signature verification error: Signing key not found


Thanks in advance for any help
