Is there an Altium model and STEP file available for the AVT9152 module?
I don't know, but if you don't get (or until you get) a better answer, it looks straightforward, there's a dimensioned drawing and footprint in the "Module Data Sheet" available at the main product page: https://www.avnet.com/wps/portal/us/products/new-product-introductions/npi/avnet-avt9152-module/
