Denoise and "old" mac

Is it fair to assume that if my 2017 MbPro running Ventura 13.6, with 16GB of memory, BUT only with a Intel Iris Plus Graphics 640 1536 MB card, aleady does not run People detection on any version above LR Classic 12.0.1, there is little point in trying to update, knowingly lose the "people" feature and expect denoise to work? Presumably it also requires over 2MB card?
