Mods like Paragliders drop items at the breaking of a spawner, even if it's with a silk touch pickaxe; this allows farming of infinite drops.
I don't know if it's feasible, but my suggestion is to alter the tag of the dropped spawner in some manner that doesn't break the vanilla mechanics. If necessary the mods devs will have to implement a check for a tag. but at least there should be something that can be checked

I have not tested with the mods you named but it's potentially fixed in the latest 1.18.2 versions. I moved the Spawner Block drops to a loot_table json file instead of an ingame event.

I looked into the code of Paragliders and they will drop Spirit Orbs regardless how the spawner block was destroyed. This means I cannot stop them from dropping.
