Best way to prevent Bambu A1 mini from updating firmware? (slrpnk.net)

Bambu A1 mini still operates on 1.04 firmware which does not include authorization "security feature". Naturally, I want to avoid it.

I know I can meddle with router somehow, even if it does not have parental controls or other very clear option to leave it inside local network.

However I would prefer preventing update in some other way, if there is any. This little printer is quite portable and I sometimes bring it to other locations. Also, remote printing and monitoring are nice features, which would be a pity to lose.

What would you suggest, or maybe have done yourselves?

Don't let it connect to the wifi/internet?

I mean, sure, you have to do the SD card shuffle, but it'll guarantee you don't end up having to deal with this.

If you have a more advanced set of network hardware (which it doesn't sound like you do) you could add a firewall rule to block traffic from the LAN IP of the printer, or for something like Unifi, simply block internet access entirely. But, even then, if you screw it up now or in the future, surprise software updates will happen.
