Is there a config we can use for it in the meanwhile? I need to work with it within a deadline.

@Fabimawn There are several boards with similar specs, for example 4d_systems_esp32s3_gen4_r8n16.

Fantastic, thats what I was looking for! I just didn't see a config that fit this ESP specifically so far since most of my boards were the WROOM variants
