Can we assign a value to empty variables?

Some of the values expect empty to disable them.
Can we use something like variable=null or variable="" to achieve the same?

An empty string should be a valid approach if the docs for that environment variable use no value / empty as a way to disable / opt-out.

Good to know, thank you!
