Are there specific 'Biscayan' (Bizkaiera) resources for someone who hates apps?

I'm tired of the gamified apps that keep pushing standard Batua when my family is from the Bilbao area. I want to move toward authentic output and stop using generic learning tools. Does anyone know of good forums, books, or community spaces where I can learn Bizkaiera-specific structures instead of the textbook versions, and how do I bridge the gap between regional dialect and the standard curriculum? I am asking specifically about learning Basque, not a generic study routine.
