Yes. It is possible. I can never remember how to do this and always need to Google (so I am writting a Q/A in hope that this will help me to remember).
The command is:
git commit --allow-empty --only
The doc for --allow-empty reads:
Usually recording a commit that has the exact same tree as its sole
parent commit is a mistake, and the command prevents you from making
such a commit. This option bypasses the safety, and is primarily for
use by foreign SCM interface scripts.
Doc makes sense but isn’t easy to search for.
