Hello @Yael Ezer ,
welcome to this moderated Azure community forum.
You have found the free training modules and paths like this one for IoT Central already.
Microsoft is not providing any other hands-on workshops, courses, or hackathons about Azure IoT.
From the community, there are Azure IoT workshops available like this one from @Wilko van de Velde although this workshop is related to the Azure IoT Hub gateway.
If you are a start-up and registered at 'Microsoft for Startups Founders hub', check the expert channel to get in contact with MVPs specialized in Azure IoT for (limited) free support.
If the response helped, do "Accept Answer". If it doesn't work, please let us know the progress. All community members with similar issues will benefit by doing so. Your contribution is highly appreciated.
