Correct. As shown in Block Diagram 8.1.1.3 on page 125 of
MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version)
Version: 0.1
Release Date: 2023-10-18
which is available publicly on BananaPi's Wiki[1].

Port 0~3 are TP user ports, Port 6 is internally linked to XGMII of MAC 0.
Port 4 and 5 are not used at all in this design.
