Change a couple of parameters in the on-board computers of these vehicles and DEF won’t be required.
Sadly the Ukraine-war supporters (the Biden Administration) won’t allow that either.

Wrong. The manufacturers rolled out some modifications earlier for certain sensors that were on months long back order, but not the whole system.
The manufactures would have to roll out a workaround, not just deleting the def system (illegal), just temporarily disabling it.
Only dealerships could do it. The dealerships are backed up on repairs now, can you imagine if every truck needed to get in there?
Then you are going to get them all back in at some point to re-enable the after market treatment?
Logistical nightmare, can’t be done. Better make the DEF fluid.
They are hoping the coming depression will slow consumption and price increases, so less goods moving, smaller economy, less trucks on the road, less def fluid.
