Crop and Upscale

Hi, sorry if this has been covered before but the only results I get from a search relate to video. I wonder if im missing something obvious, but there appears to be no option to crop a photo before upscaling it when using s RAW photo. Cropping in Lightroom has no effect because the plugin extra for RAW imports the full RAW file anyway. This leaves a huge file sat in the Lightroom library that isn’t needed. Is there a way to crop and upscale within PhotoAI so you are only upscaling the bit you want in the final image?
