Google Business Profile Updates.......... Do they help with SEO?

I have a small local plumbing based service company in the US. I've been looking for ways to boost the SEO for my Google Business Profile. Does anyone know if it helps to make regular Profile Updates? If so... how often should I do it? Also... I was thinking about adding pictures of my work that have local geo tags... Will that help? Should I take one picture a day and post it? One picture a week? Thoughts? I'm trying to kill it with proper Google reviews that have pictures and a comment. Anything else?
