How did you figure these bulbs are bad ???
Have you tried with HEADLIGHTS HIGH BEAMS ON ?
Do not stare at light bulb directly to prevent retina eyes damage.

High beam circuit...
All right, your chassis has a 2x non-working high beam incandescent bulbs.
The bulb power is controlled by F-SAM acting upon messaging from SCM stalk sensors.
Usually headlights are fused individually L /R... so missing both highbeams is unlikely a fuse issue!
-- The best way to diagnose solderless SCM module is to test using a compatible scanner to exercise it live.
-- You will easily read activation status under 5mn without any disassembly.
-- You will be able to toggle lights on/off
Let us know test results.
