This node is connected to the m.2 slot found in orange pi 5 pro and certain pins are connected to the gpio, like PCIE20x1_1_PERSTn_M1, PCIE20x1_1_CLKREQn_M1 and PCIE20x1_1_WAKEn_M1.
In absence of these gpio definitions, would cause nvme to be recognised but if it went to sleep, there is no way for them to be waken up. Hence, Adding this resolved the issue -
