Are the tank weapons eg 84mm recolless anti- tank can destroyed this too ?....

As long as enough rounds lands accurately on the vulnerable part of the tank, like the engine area, the turret roof or even any hatch left open by the tank crew.

And how to be that accurate ? Drones with explosives..esp FPV drones...

BTW, it was the Ukrainians who "taught" the Russians how to use consumer (toy) drones on the battle field during the early stage of the Conflict...
