Obfuscation of .net core 7 multiple dll's at once through commands

Hi i recently got to know about redgate and its obfuscation of .net core  dll obfuscation , i downloaded 14 days trial version to verify the same.
But i need a command to obfuscate all the dll's at a time, so can you please let me know the solution.
based on this we will evaluate the tool and plan to buy this product.

Thanks ,
