Updating Firmware without wireless connection

I am fairly new to the Bambu Lab A1 mini and i was wondering if there was a way round to update the firmware without the need for internet connection?
I am currently onboard a cruise ship and i am unable to connect the printer to our ship network for security issues. I was wondering how it is possible to update the firmware without the need for the internet connection.
Thanks to everyone for any advise, i appreciate your time and patience with me.

Welcome to the forum.

Unfortunately there isn’t a way to update firmware offline. Is there any chance you could hotspot a cellular phone at a port of call?


I guess i can give that a shot, i hope i can pick up a signal . But otherwise thanks for the info.
