No, the headlamp assembly is a single unit.
The head light is a sealed unit. The outer sense is not removable.
The lenses are not removable from the headlights. They are one assembly.
The answer to how to clean your headlight lens depends on how dirty your lens is. If it just has bug juice and road grime any good car soap will clean it, just be carefull not to scratch the plastic. However if your lens is really yellowed or the clear coat cracked then you will need kit designed to clean the lens.

If a plastic lens, drill a very small hole at the bottom to let water drain out. If a glass lens, you will have to replace.
To separate the headlight lens from the headlight housing in a BMW Z3, first, ensure the headlight assembly is removed from the vehicle. Use a heat gun or oven set to a low temperature to soften the adhesive holding the lens to the housing.

Once separated, clean any old adhesive from both surfaces before reassembling or replacing components.

Using Deep Woods Off, which is an insect repellent, to clean a headlight lens is not recommended. While it may temporarily remove some grime, the chemicals can potentially damage the plastic lens and affect its clarity over time. It's better to use a dedicated headlight cleaner or a mixture of soap and water for safe and effective cleaning.
