I don't want to send the screen using the NVIDIA graphics card, but instead use the Intel built-in graphics to send the screen

Graphics / Linux Linux

I’m using Ubuntu 18.04
I’m using i7-10700
I am currently using the RTX3090.
I connected HDMI to Intel’s built-in graphics.
If you type nvidia-smi, xorg is running.
If this process is forcibly killed, the GUI is terminated and the CUI environment is transferred. I want the RTX3090’s process to be nothing.
I want to display it using Intel built-in graphics.
I don’t know if this question is right for you here, but I appreciate your answer.
