This router is Raisecom MSG1500 X.00, which is customized by China Telecom.
SOC is mediatek mt7621, wifi is a single MT7615DN chipset which provides 2.4G & 5G communication.
The hardware of 5G has a LNA and PA.
Nand flash capacity is 128MB.
After installing openwrt master firmware, 5G configuation shows that max power is 6dBm.
Following is the openwrt version:

Research direction
Start by reproducing the 5G power limit on the Raisecom MSG1500 and inspect the attached EEPROM data alongside the MT7615 power and calibration handling. Done means the device no longer reports a 5G maximum power of 6dBm, with the result validated on the reported hardware.
