I agree with @gbenrus25 about it not being best practice to place a smart bulb on a dimmer. That said, can you configure the dimmer to be an on/off type device so there is no ramping and dimming? Either way, I have half of my house on Leviton/HAI Dimmers with all iLumin Bulbs and the other half with Inovelli Red Dimmers with the relay set to provide constant power. I can tell you that I left my Leviton/HAI dimmers with a ramp up and the iLumin’s have been fine at 100% power without issue for more than a month. They will turn on at lower levels of dimming but you can tell that this isn’t ideal so I would say that you can do as you proposed in your rule. Just make your dimming speed as fast as possible or eliminate the ramp if possible and you should be fine. For reference, I have about 25 of my bulbs on the old Leviton/HAI dimmers with 0 issues. Slowly as we remodel room-to-room, I am moving to my Inovelli Red Switches though.
