Can a scene ignore parts of a device/entity?

Configuration
1

I have one of those thin LED strip lamps that can, in addition to displaying solid colors, display changing patterns of colors and gradients. It’s part of the Tuya ecosystem, so I use the Tula integration with it, but the integration doesn’t understand how to configure it for gradients (nether static nor moving); it just lets me choose on/off and one color.

The problem I have is when I have it as part of a scene. I can use the remote that came with the stick to choose a certain gradient that I always want, and then I just want HA to turn the stick on and off (retaining the gradient it last had). The problem comes in because, when I add it to a scene, HA seems to want to have a setting for the brightness and the color. I’m pretty sure that I could hand-edit the YAML to exclude the color information, but I’d really like to use the GUI where I can.

Is there a way, with the GUI, to tell scenes to not record any color information about the device and to just turn it on/off or set brightness?

What about making a virtual entity with just on/off script that call the led strip and then include that device in the scene instead of the Les strip?

I don’t think there is a way through the GUI.
IMHO, recording all the attributes by default makes the GUI pretty much useless, tbh. It should record the state and, optionally, some attributes you indicate, although that would probablt make the UX cumbersome.

As you (I guess), I go into the scene YAML and remove the irrelevant attributes.
