Firmware update

[Hayabusa]

it keeps prompting me about firmware update required. Do I/should I do it?
Can it be undone if I don’t like it it messes something up?

It's up to you. I like to run the latest version, so I always update after new versions are known to be stable.

Can it be undone if I don’t like it it messes something up?

Yes. See this thread for more details on what's involved in downgrading to older versions not available in the DJI Assistant 2 app.
