Hi Sumit,
Thank you for asking this question on the Microsoft Q&A Platform.
As per https://learn.microsoft.com/en-us/credentials/certifications/renew-your-microsoft-certification-faq
Can I renew my certification by passing a beta exam or by retaking an exam before my certification expires?
No. You must pass the renewal assessment for your certification on Microsoft Learn before your certification expires; no alternative paths are available to renew your certification. There are no exceptions to this policy.
Regarding the scheduling, contact directly the exam provider - the relevant info is available at https://learn.microsoft.com/en-us/credentials/certifications/azure-administrator/?practice-assessment-type=certification#certification-take-the-exam
