Can we target SDK v2.0.0 and modem v1.3.1 to run on AT&T?

According to the Nordic infocenter here 

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcomp_matrix_nrf9160%2FCOMP%2Fnrf9160%2Fnrf9160_operator_certifications.html&cp=2_0_3_4

Modem v1.3.1, SDK v1.8.0, lwm2m_carrier v0.21.0 is certified for use on LT&T network.

When building firmware for our product which is operating on AT&T, do we have to target v1.8.0 of the SDK (with its corresponding lwm2m_Carrier library)?

Or can we upgrade to v2.0.0 of the SDK?

I don't want to get into a situation where I am debugging issues which have since been fixed in v2.0.0 of the SDK. I see that the lwm2m_carrier library is optional for AT&T, and since "Functionality from the LwM2M carrier library is one way to fulfill the requirements" then presumably we would be safe to update at least the lwm2m_carrier library (if it is in fact compatible with v1.8.0 SDK?)

Summary: what version MUST we use for compliance with AT&T?
