Is the use of EDCH without ephemeral key generation considered best practice?

Struggling to find the answer to this, from a best practice perspective should we be mandating the use of ephemeral key generation?

Current approval ciphers include TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384 at 265 key bite length and ephemeral key suggested but not mandated.

On looking this up the cipher is showing as weak without ephemeral due to PFS not being supported.
