Issues printing in Lan from external feeder with AMS attached

Hi, First post here, so if this is already answered, please point me in the right direction.

I am wanting to print
In LAN only mode
From the external feeder
Whilst the AMS is still attached

I can do this through the cloud.

However, when I set up a gcode file and print from the card slot, my filament setup constantly changes from the external feed to AMS.

Unplugging the AMS is not an option, and it needs to remain plugged in - why - I am paraplegic and reaching these plugs isn’t at all accessible without the help of others who are not always about to help.

I cannot use the screen to re-change the filament to the external feed.

Thank you for your input
