Use homeassistant.local but call assist from Nabu Casa

I have my wall mounted tablet dashboard running homeassistant.local so that it is quicker and works without internet connection but this is a limitation for Assist as not being https (and I do not want to go throught complex config to enable it) I cannot use the voice with it.
If I run the action: assist it open the assist on homeassistant.local, is there any way that I can let it call the Nabu Casa assist ? So I can maintain my wall tablet local but just for voice assistant using Nabu Casa https connection.

Thank you
