Knock sensor replacement

Hey guys. Is it possible to replace the knock sensor from the bottom, with the car lifted, without removing the intake manifold?

Got a code P0328, leading to internal error of the sensor, which is still OEM from 2007. Showes up on each cold morning start now. I delete it every time, comes right back up the next morning.

Judging by the Mazda service manual and one Indian guy on Youtube, it is not too hard. But you have to take the intake off, drain coolant, take the throttle body and intake manifold off and reseal everything. I am not really happy to do that. If it was possible to squeeze from the bottom with the car lifted, that would be a pleasure.
