How to Secure/Protect your code/nupkg

Hi, i have this bot that i want to implement on Client machine, but he can see the nupkg downloaded by UiPath assistant and see its content or modify it.

My question is how i can prevent this? is there a way to secure the code? or make it locked?

it needs to be a solution to implement the code on client server/machine, i cannot alter the windows permisions, because client will always be admin and can access everything

Yes but what if you are not the Administrator of the machine
