Well I think compiler has options to generate warnings based on the MISRA or other coding standard chosen in the project settings. Everytime there is a HAL update, so your build will let you check it. A "certificate" to doenload may not be the best option.

MISRA compliance requires a lot more than just running a checker over the software - full details are available in MISRA Compliance:2020. In addition, I have not yet seen a MISRA checker within a compiler that offers support for all of the MISRA guidelines.

A compliance statement for something like the HAL is also only ever going to be a part of what is needed, as its use within a project may render parts of the code (in the HAL or the application) non-compliant.
