A secondary ip address seems to be automatically added to a nic which causes several issues in our setup.

You failed to show the configuration of eno4's profile in Network Manager (nmcli con show eno4). You can use 'nmcli con edit' (or nmtui) to modify the profile to eliminate the assignment of the unwanted address -- if it is in automatic mode (which seems to be the case) then you may need to fix your DHCP server instead. If there is no chance that Network Manager is assigning the extra address then you will have to hunt around your system for the program or script that is doing so.
