Yo!

I have tft24 and its operates on both modes. You can change it at any time "live", but you have to connect both set of display cables (tft and lcd). Also you need proper firmware directly in tft24 provided by BTT for those modes.

So you have Ferrrari with max speed of 10 mph. Why 40 steps on such a powerful configuration with 32bit board and 256 steps drivers?
You have misalignment between hardware and software steps, thats why you have your printer head all over the place.

First you need to explain your board over driver slots pins how many hardware steps has a driver (over MS 1,2,3), than you have to "clear it out" with Marlin what hw do you have (over steps/mm). In 2208 case you have hw "preparation" and sw "conclusion" for drivers.

Here is how to install Marlin and pin table for BTT 1.3: https://raw.githubusercontent.com/bigtreetech/BIGTREETECH-SKR-V1.3/master/BTT%20SKR%20V1.3/BIGTREETECH%20SKRV1.3%20guide%202019%20-%206.pdf

Great video for you, you can use it on delta too: https://www.youtube.com/watch?v=duNHOPlh2Pg

My 5c: go for lv8729. Its very cheap, all hw, 1/128 are more than enough for deltas, kids level installation etc...
