Is there a way to bring to 0 Section Height on full bleed image blocks?

When modifying a full bleed image block I get the parameter 'Section Height' (S,M,L) that I can bring up to 10 leaving a small space at the top and at the bottom of the image. I would like to get rid of this space by bringing the section height to 0. Is there a code that I could use to achieve that?

Thank you.
