//This works for the 2.9 inch black and white display. Add pin numbers.
GxEPD2_BW<GxEPD2_213_flex, GxEPD2_213_flex::HEIGHT> display(GxEPD2_213_flex(/CS=5/SS, /DC=/ 33, /RST=/ 27, /BUSY=/ 32));

No, or only by chance. You use a constructor for a 2.13" e-paper display.
GxEPD2 doesn't support the 2.9" flex e-paper display. It might work per chance, Iif the display you select has the same controller.
