Has Cloudflare taken away ability to switch certificate authority to DigiCert for Universal SSL Edge (Free plan)?

I have followed the recommendations for several zones.

The response is
{“result”:{“enabled”:true,“certificate_authority”:“lets_encrypt”},“success”:true,“errors”:,“messages”:}

It has no effect. Сertificate Authority is still Let’s Encrypt.
Site continues to give the Let’s Encrypt certificate.
