From document Quectel_BG95BG77BG600L_Series_QuecOpen_Application_Note_V1.4.pdf, page 23, it appears that BG95 pin 18 has signal/port name GPIO5, which in turn can be configured to be GPIO_3 or I2C1_SCL.  This matters because the eval board breaks out a limited number of test pins on J803, J805, J806 and J804.  On J804 there is a pin designated as I2C_SCL.  In document Quectel_BG95BG77BG600L_Series_QuecOpen_Application_Note_V1.4.pdf there are references only to I2C1, not any other numbered I2C peripheral.

^ Choosing a test-able GPIO for GPIO demo app

Following GPIO pin table from QuecOpen gpio demo app: 

 52 /*  !!! This Pin Enumeration Only Applicable BG95-OPEN Project !!!
 53  */
 54  #if defined(_QUECTEL_PROJECT_BG95)
 55 GPIO_MAP_TBL gpio_map_tbl[PIN_E_GPIO_MAX] = {
 56 /* PIN NUM,     PIN NAME,    GPIO ID  GPIO FUNC */
 57         {  4,           "GPIO_01",      24,      0},
 58         {  5,           "GPIO_02",      21,      0},
 59         {  6,           "GPIO_03",      22,      0},
 60         {  7,           "GPIO_04",      23,      0},
 61         { 18,           "GPIO_05",      3,           0},
 62         { 19,           "GPIO_06",      2,           0},
 63         { 22,           "GPIO_07",      1,           0},

From document Quectel_BG95BG77BG600L_Series_QuecOpen_Application_Note_V1.4.pdf, page 23, it appears that BG95 pin 18 has signal/port name GPIO5, which in turn can be configured to be GPIO_3 or I2C1_SCL. This matters because the eval board breaks out a limited number of test pins on J803, J805, J806 and J804. On J804 there is a pin designated as I2C_SCL. In document Quectel_BG95BG77BG600L_Series_QuecOpen_Application_Note_V1.4.pdf there are references only to I2C1, not any other numbered I2C peripheral.
