If someone is having trouble because they cannot copy the image to a 32GB SD card, because there is a few bits less space on the card. I recommend the following:

The solution may be to first copy the image to a larger, for example 64GB uSD card (use balenaEtcher prg).
You start the RPi with the 64 GB card, then copy it back to the 32 GB card with the SD Card Copier program.
To the card you couldn't copy to because there wasn't enough space. This is the simplest solution.
You don't need shrink, you don't need linux os. By the way, the sbitx_v2 image takes up about 9 GB of space.
?
Yes, I tried it and it works.
