Power BI dashboard or tiles can now be added to Dynamics CRM personal dashboard. But they can't be added to entity forms. Request to allow them to be added to entity forms, so when a user opens a record, he can view the Power BI reports in the form.

Although it is supported to add an Iframe in the form to link to a Power BI report, but it requires some development work. If it can allow users to add them through UI, just like they do from the personal dashboard, it will be more convenient and intuitive to expand the power bi usage with Dynamics CRM.
