I was trying to Upcale in Photoshop (Creative Cloud subscription) as LRC does not allow upscaling if the denoise option has been used, and there is no Generative Upscale option in the Image dropdown. What am I missing? All apps have been updated

Run Denoise on the RAW file, then export as a TIFF. Import that back into Lightroom and use Super Resolution. Make sure to do Denoise FIRST and not the other way around. I’ve been doing this with older Sony files (A100 and A700) and it works reasonably well. Watch closely for weird artifacting in hair especially though.

Is it missing or grayed out? I have only tested with 8bpc data. Is the file a higher bit depth? I’m not in front of my computer to test.
