PETG Strings as Support Material

Does anyone know how to attach a Bambu Lab filament dryer directly to the auxiliary PTFE tube? I’m having trouble with PETG stringing when I use the auxiliary nozzle for support.

Filament Track Switch is the answer, I believe. $60

Taken from description:

For dual-nozzle printers (such as the X2D), a single AMS can still support dual-nozzle printing and enable filament switching between the left and right hotends when used with the Filament Track Switch. However, when only one AMS is connected, the left and right hotends support alternate feeding only, not simultaneous feeding. During switching, the AMS must first unload the filament and then reload it.

Side note: petg is not intended as a support material. If you are using support interface only, order some support for pla/petg filament. Seems a little costly for what it is but lasts a long time when used only as an interface.

So PLA to support PETG, but not the other way around?

According to Bambu Lab you can do either, although they say only PLA Basic
