I’m not sure I’m understanding - when you reference the bridge, do you mean the MyQ unit that sends the signal to the garage door opener?
In any case I thought the MyQ should be able to close without the delay when it does the proximity-based auto-close from the Tesla, since you are within visual range of the door and could confirm the coast was clear for the door to close. Also if that doesn’t work that way, they shouldn’t have this feature listed on their website.

Does you opener have MyQ built into it, or are you using the “Smart Garage Control” in that ad? From my experience the instant close is only with the separate smart controller.
If you have MyQ built in, if the signal comes from an internet based signal, it will have a delay in order to warn people. MyQ doesn’t know if you are sending the signal via the Internet from 5’ away or from 5 states away.
With the smart controller there are/were 2 versions (at least there were), one with a built in light, the other without. The one with the light, would delay and flash it’s own light, the one without didn’t.
Unless Chamberlain developed a separate API for Tesla that makes it behave differently, any Internet based signal to a built in MyQ opener results in the flashing/delay. If their smart garage controller (add on to work with any brand garage opener) doesn’t have the light, it would be instant.
The Homelink upgrade is just worth it. I use my phone app when I’m not in the car, or if I want to open the door for other people (deliveries, family, pest control company, Amazon in garage deliver). But in the end, for a vehicle, nothing is better that a direct signal.
Also, if your internet goes down, MyQ will not work. Assuming your power is still on, you can still open the door with homelink/remote.
My 3 is a 2019 with homelink, and my ’21 Y didn’t, but I had it installed the day I took delivery.
