Paul,
Did you consider using reorg while active?
I created a little utility (few cdl and querys) that automatically runs once a month.
Removes all deleted records from all files, unattended.

We're working on a huge file reorg project. We have a 17TB system that's over 75% full. We have determined we can get down around 50% by getting rid of deleted records. Once we accomplish that, we'll change over to reusing deleted records.
RMVM beforehand and ADDLFM afterward has always been the way to go to avoid thrashing. But that was before the proliferation of SQL indexes.

That's probably it. If I add the index back after a file reorg, will
that set me up for level checks?
Ah. So the inquiry from the OP is regarding an intention to disable the keyed Access Path (ACCPTH) [maintenance] during a Reorganize Physical File Member (RGZPFM) against the underlying data?
So perhaps the AccPth of the INDEX is defined UNIQUE, thus preventing changing the Maintenance (MAINT) attribute? In that case, the DROP INDEX [or Delete File (DLTF)] can be used after a Save Object (SAVOBJ), and the Restore Object (RSTOBJ) done afterward -- there could be two restores, one first without the member, and then another to restore the member, but there would be no point in so doing.
FWiW the ALWCANCEL(*NO) reorg will already disable a non-unique keyed AccPth, and move the rebuild until afterward in an async runpty-52 QDBSRV## system job. And a non-unique AccPth could be modified with Change Logical File (CHGLF) to set the Maintenance (MAINT) attribute to the special value of *REBLD [¿possibly required?: in conjunction with RECOVER(*NO)].
Maybe some background about the scenario, to help explain the reasoning for the approach; perhaps discussion can lead to a different path.?
