Modify a password of a 'Source Control' type credential in command line

Hi,
I use AWX 17.1.0 on Linux CentOS server.
How to modify a password of a ‘Source Control’ type credential, in command line under Linux CentOS?
Regards,

Is awx-manage an option in 17.1.0? I had to use that to change a password in 21.10.2. (You can open a terminal to the web node and try running awx-manage to see whether it’s there.)
