Is there a way to set environment variables without a value while creating a Azure Container Instance?

I want to create a Azure Container Instance by using the website ( The original docker command would look like this: docker run -d my/image --min-port=49160 --fingerprint.

On the advanced tab, I can enter a combination of key and value, for example min-port and 49152. But I also need to set fingerprint as key, without a value. This is not allowed and gives me an error message “Value must not be empty”. Is there a solution, maybe with CLI?
