Generally the chair can (and perhaps should) take the sense of the meeting and decided that certain matters may be contentious and so move them down the batting order, perhaps to get procedural matters out of the way first.
If any owner objects to this, they can raise their objections and call for a vote that the order remain the same or be changed differently .
It helps a lot if strata committees have standing orders that cover this kind of thing but almost none of them do.
And, generally speaking, the chair is in charge of the meeting, so changes must come from or through them.
Why do you ask?
