You can ask for Service to remove - probably get charged $200 per hour for labor.
I removed it from my Model 3 (2018) installed it to my Model Y and scheduled service. Mobile tech enabled the HomeLink function - no charge.
You can probably skip the "removal" labor cost if you unplug the HomeLink module, DiY, from your Model 3.
Caveat - the HL module on older Model 3 are installed in front of the front bumper steel beam which requires removing the plastic bumper panel. It's a lot easier to unplug the HL module if it was installed under the frunk vs front bumper beam.
