@Bogdan Dragu Thanks again for your query, post validation with our team it has been called out that customers will not be able to remove/exclude/hide this information message from the dashboard. Apologies for any inconvenience this might have caused.
Our team has taken it has a backlog item to explore possible options on how to hide the information message , however for it to be prioritized would request you to create a new feedback item in our feedback channel, which would help the user community to upvote & comment on. This allows our product team to effectively prioritize your request against our existing feature backlog and also gives us insight into the potential impact of implementing the suggested feature.
Thank you, please feel free to circle back if you have any further queries.
