Why would you ask a doordash to do this? You need someone who is an expert with comparing similar real estate. They are also an expert with measuring. That's part of an appraisal... so they can't sketch a house either? They're an expert at what features of the house bring the most returns for the money. That's done in an appraisal so they can't help design a house either? They're also an expert at verifying property information... they can't do that either?
Sorry but your argument is full of holes. They aren't doing an appraisal, nor is there assignment to provide an opinion of value, nor is there any assumption that one is being done. Therefore, there is no appraisal. They aren't acting as an appraiser; they are acting as a expert measurer, sketcher, valudator, home expert, conditions of sale expert, etc. Of course USPAP will allow you to do it. No Q&A necessary.
