Can we create parameterized procedure for standard objects in Salesforce like contact, account, opportunity etc.. attached is the screenshot of one of the business logic which I want to call out using execute anonymous window. I’m new to Salesforce.

I have created a custom approval prcoess on a custom obejct in Salesforce and my requirement is to update comments on the ProcessInstanceStep Object, but as per documentation we can not perform DML on PrcoessInstance or ProcessInstaceStep Object. How to achieve this requirement?
