Hi @daversintel
Thanks for the PR
Could you please take a look at #4666 for all the different locations new options have to be reflected and add the new option accordingly? While not all options are necessarily required immediately in all wrappers, not adding new options right away causes mistakes down the line (someone else may adds new option to the wrapper at a place where your option would be)
Otherwise, looks good to me 👍

Perhaps option description can be expanded as well?
"Enable Laser On constantly (GS SKU Only)" is not very clear.
I'd suggest something like - Keep laser active in-between frames as opposed to just during frame exposure, thus improving multi-camera performance consistency (relevant for global shutter devices only - D430, D435 and D435i)

[daversintel]

The option description is updated as suggested except the device models since it will also apply to new coming devices.

It looks like not all the options are in all the wrappers. Not sure which wrapper should have this in. Can your team handle the wrapper part?

[dorodnic]

@daversintel - for this PR to be merged, new option must be added to wrappers.
You can use #4666 as reference for which files need to be changed.

This should be added to all the wrappers as well. See #5208 for an example.
