Nah. The Switch was Nintendo picking themselves up after the Wii U's failure and giving it another go. It was a late arrival to gen 8 the same way the Master System was in gen 3 after the failure of the SG-1000 (also a gen 3 console).
The prospect of calling the Switch a full fledged gen 9 console next to PS5 and XSX is a bit mental tbh. These new boxes do things even the PC currently doesn't and both have desktop class everything from CPU to GPU's. If you must pit the Switch directly against these gen 9 consoles as a console then it's going to look a bit silly.
It's competing in it's own space the same way all other Nintendo consoles have since the Wii. But i'd class it as a gen 8 system (if we insist it's a full fledged console and not a 3DS successor, which could then be called a gen 9 handheld).
