New CM4 issue with Raspberry Pi Display

We have encountered issues with the new generation of Computing Module 4 and Raspberry Pi Touch Display (7 inches). It is not working properly, the display does not turn on. We install the latest dtblob available from the Raspberry Pi website. It has been tested with Raspbian and it’s working fine, but not with Balena OS.

Does anybody else have to encounter the same issue ? Do you think it could be something related to Balena OS ?
