Tried the below command but not really help somehow:
no errdisable detect cause gbic-invalid
Digging into Cisco documentation, “Errdisable Port State Recovery” can be configured using hidden options (you can not “Tab” it out) such as below
show errdisable detect
TestSW01(config)#errdisable recovery interval 120
It is to “auto-recover” when errdisable is triggered on a particular port
wait for some time like 1 minute

Thanks for your comment, since most of the posts are experiences from work, it makes it easier for me just share my knowledge without worrying about the actual writing.
