A Frame Relay frame typically consists of a minimum of 2 octets for the header and can have a variable size for the data payload, which can range up to 4096 octets (or 4,096 bytes), depending on the configuration and network conditions. Therefore, the total size of a Frame Relay frame can vary significantly, but the header is fixed at 2 octets, with the remaining size allocated for the payload and any optional trailers.
In the Telecommunications book on Page 180. The answer is Yes it does have a fixed-length frame of 53 octets.

Frame relay.
Leading two octets of message digest: L, To enable the recipient to determine if the correct public key (k(A) e ) was used to decrypt the message digest for authentication, by comparing this plaintext copy of the first two octets with the first two octets of the decrypted digest. These octets also serve as a 16-bit frame-check sequence for the message, for authentication and error detection.
