There is no way to get a 10-speed indexing shifter to index with an 8-speed cassette. The cog spacing is all wrong. If you want to use the 10-speed barcons with an 8-speed cassette, you are going to have to use it in friction mode.
As to a 10-speed shifter with a 9-speed cassette, you set the derailleur's inner limit stop to prevent it from traveling too far and effectively block out the 10th click.
