How to export a blender animation with certain bones/limbs not included?

Not sure if this fits here since it uses a plugin but I don’t know where else to ask.

So my issue is basically this: I want to export an animation made in blender and import it to ROBLOX. That part is just fine, but how do I export said animations with certain bones not included?

For example, I don’t want to include the entire left arm and both legs. I could go through the animations in the studio animation editor and remove each limb from the animation manually but that’s a lot of work considering there will be several hundred animations.

Is there any way to export these without certain limbs being animated at all?

Sorry, for a little more context, the reason it would be an issue if these limbs were included is because they’d override the movement animations.
