Studio XIAO nRF52840 (Sense) battery pins number

Hello Everybody,
I know it is an old post but I’m struggling with an issues about reading the battery charge.
I’m using an XIAO nrf52840 Sense, with Arduino IDE 2.3.4.
I noted that the VBAT_ENABLE is associated with PIN 14 that is teh same for blue led. So when I put to LOW the VBAT_ENABLE for reading the battery voltage level the led blue switch on.
Any suggestion for solving this issue?
