Is there a way to reduce upgrade checks and reduce log clutter?

My logs are cluttered with cs-cart checking for updates many times a day. I see many pages with just this check and finding anything is difficult.

Is there a way to reduce this unneccesary check to 1 time a day?

That would actually make the logs useful.

In Settings > General, you can uncheck 'Check for updates automatically' which will still let you check for updates manually via Administration>Upgrade Center.

I would imagine changing this to limit the upgrade check, which actually combines with the license check, would be a breach of your contract with CS-Cart for use of their software. Only CS-Cart could authorise for you to make such changes.
