AZ-900 exam free voucher Azure

Hello,
I recently finished Azure Fundamentals (https://learn.microsoft.com/en-us/credentials/certifications/azure-fundamentals/?practice-assessment-type=certification)

But I see, to take final exam and then claim certificate, it is needed to pay around $50-$90 based on region.
So my question is, are there currently any absolutely free vouchers for that exam? -100%

I have been looking for it for around month, still no clue.
