Cryptography DRBG

I'm trying to figure out if the DA14585 meets these requirements:

• The accessory must use a Bluetooth controller that meets the following requirements:
     LE 2M uncoded PHY
     Data packet length extension
     Bluetooth Core Specification Version 5.2 Feature Overview.
• The Bluetooth LE transmit power level of the accessory shall be ≥ +4dBm.
• Support 15-minute key rotation using hardware timers.
• A cryptographically secure DRBG (see NIST Special Publication 800-90A) with a reliable source of entropy (see NIST Special Publication 800-90B). Does the DA14585 have a built-in source of randomness? 

I think the LE 2M uncoded PHY and Data packet length extensions are supported.

Would I need to add an external LNA to meet the +4dBm?

Does Dialog have a secure DRBG (Deterministic Random Bit Generator) library or example for the DA14585? I've been using the TRNG, but am not sure if it qualifies as a DRBG.

Thank you for your support!
