Since v1.2.0 came out for odyssey, many wall clip glitches used by speed runners were patched out.
This forced them to buy the physical copy and reset factory their switch, turn wifi off, etc. just to get the game back to 1.0.0, since if you try to update the game it will automatically update to the latest version, so already there's no clear solution to get odyssey back in v1.1.0, even with the physical copy.
This is really inconvenient to have to buy the physical copy and reset factory the switch just to play odyssey in v1.0.0, yet I do realize that some still speedrun the game in 1.2.0, but generally 1.1.0 speedruns have proven to be more successful (according to the current leaderboards).
Is there really no other way to downgrade to 1.0.0 or 1.1.0 with the digital copy of Super Mario Odyssey or any other digital game realistically? This is very annoying and obscure … perhaps there's a work around procedure for this?

Since the cartridges don't change version like in the N64 days, you have 2 choices. Starting at 1.0 on a wifi disabled switch with the physical game; or playing on the latest version on digital/wifi enabled switch.
The only way to play 1.1 (or any version between 1.0 and latest) would be to
Both options seem like pretty hard to do as of now. So I would say you will have to give up. The records that are recorded in the 1.1 version are now pretty much untouchable and skips/glitches that were available only in the 1.1 version are now unusable.
