Hi Patrick and welcome to this forum!
tl;dr: sadly, the simple answer is no.
This binding is a rather simple fork of a Neato Binding, which uses the same API.
According to its documentation (found here), the cleaning mode is a read-only parameter and cannot be changed.
It seems to be generally possible (some clues here) so you may want to to ask your question in the Neato thread here but I’m unsure whether it is still being maintained.
Frankly, meanwhile I’ve moved on to another vendor myself and can offer but limited support.
Still, if you have any ideas or clues, please don’t hesitate to contact me again.
