Just apply some black pvc tape to mask-off parts of the sensor - they
can
have a wide angle of detection and you may need to experiment a bit.

Depending on the tape, black insulation tape can be pretty transparent
in the thermal IR - you may be better off using it to stick down
aluminium foil.

Insulating tape should be OK though, as it's only to try to reduce the
sensitivity of, or deflect it slightly off, the IR detector.
