I also work with palo alto and I don't think there is such option in F5 cli preferences (https://support.f5.com/csp/article/K77130210) for example to see the running config as "tmsh xxx" similar to the palo alto "set" output. You can only see it in JSON format :(
You can still see some possible options below:
F5 SCF config files:

Youcan export/import some config in CVS format:

You can also copy and paste large config blocks from a terminal:
