how do I just remove the single ADDRESS I added as an alias ? not the whole
thing ?
You first remove all ipv4.addresses and then add the one you want. Then you save/activate.
That's not necessary. For any setting that can be multi-valued (such as addresses and routes), you can prefix with + or - to add or remove just one entry. For example, to remove just address 10.1.1.2/24:
nmcli con mod em1 -ipv4.address 10.1.1.2/24 nmcli con up em1
