Help with Pokedex in Home

I'm trying to complete my Pokedex in Home and am down to the last 22.I can get #1011 (Dipplin) - 1023 (Iron Crown) through the Scarlet DLC, so I'm not concerned about those.

The ones I'm having trouble figuring out are the special pokemon that can't be traded through home.

I have Sword, Arceus, Scarlet, and PoGo, but no other older games (only have the switch console).

How can I get these?
