The only hitch available that will fit on the 2019 Volvo V90 R is the Stealth Hitches # SH67FR, which can be used to carry bike racks, but there is not currently available wiring to allow for towing. This is a custom fit hitch for the V90 that will install behind the bumper and because the receiver is removable it won't affect your ground clearance nearly as much as a standard hitch.
I've linked an installation video of this hitch for you to check out, as well. view full answer...
The hitch you're looking for is the Stealth Hitches Hidden Rack Receiver # SH67FR. This is the same as the SHR33003 you were looking for. This hitch has a max tongue weight of 600 lbs and will allow you to carry hitch mounted accessories with your 2023 Volvo V90. If you plan on towing you want the # SH67FRT instead. This includes the towing kit which has the ball mount and wiring harness. You can also add the towing kit later using the # SH36FR. view full answer...
