I’m currently in the process of interfacing a 320x160 mm LED dot matrix with P4, of 80X40 RGB pixels to an ESP32, is it possible to use smart matrix libary to interface with that?

I see you found this already:
SOLVED!
For my matrix P4(1921)-80x40-10S-V20 in MatrixCommonHub75.h file added new SM_PANELTYPE - SM_PANELTYPE_HUB75_40ROW_80COL_MOD10SCAN with parameters:
MATRIX_PANEL_HEIGHT 40
ROW_PAIR_OFFSET 20
MATRIX_SCAN_MOD 10
COLS_PER_PANEL 80
And in file MatrixPanelMaps.cpp for SM_PANELTYPE_HUB75_40ROW_80COL_MOD10SCAN case added map:
const PanelMappingEntry panelMap80x40Mod10 =
{
{0, 7, -8},
{0, 23, -8},
{0, 39, -8},
{0, 55, -8},
{0, 71, -8},
{0, 87, -8},
{0, 103, -8},
{0, 119, …

This information is not enough. You need to know such a panel parameter as scan, and preferably also the driver types
