E-ink 1.54 and HSPI on esp32 #22

Hi all!
We chose a good screen that we needed for a long time and settled on E-ink 1.54 https://heltec.org/project/154-e-ink/

The board was created (main controller ESP32-wroom) and we started the code. We figured out the library, but do not fully understand how it can work.
We’re having a problem connecting to the SPI.
The fact is that we have the following connection for our esp32 board (it has 2 SPI - VSPI and HSPI):
The screen is connected to the pins:
e-ink HSPI
cs-15
mosi-13
dc-12
clk-14
bysy - 27

another sensor module VSPI
ss - 5
sck - 18
mosi - 23
miso - 19
busy - 17
When I use the eink library I get problems because the library uses the call to SPI.**
which by default uses pins VSPI.

But my physical connection is different. Please tell me how can I be?
I have no options to change the connection. I ask for your help in setting up the library to use the screen connected to the HSPI pins
