Hi Martyna, I hope you are doing well.
To answer your question, other elements of Blue Prism like Hub and API can be installed locally without issue. Things like certificate setup in the Hub documentation are designed with local proof of concepts in mind. The only consideration would be the requirements for Hub and API, like being able to use IIS on your machine to host them.
I hope this information is helpful! Please let me know if you have any questions for me.
