Hello @Yaren Özkurt
You might first check the RDS CAL version compatibility by reviewing License your RDS deployment with client access licenses (CALs) | Microsoft Learn
When it comes to licensing and compatibility concerns, it’s recommended to contact Volume Licensing Service Center for most reliable information. You may reach out to Volume License Key Phone Numbers | Microsoft Volume Licensing or Remote Desktop Server Licensing (microsoft.com)
Best regards,
Karlie Weng.
