NodeMCU ESP 32S2 with SPI ST7735

Hi, I’m using ESP - SPI - connected TFT LCD with ST7735 chip. This model does not have possibility to control the backlight. Is there any way (as solution) to switch off/on this LCD (power disconnection) with possibility to reinicialize it (SPI bus) without ESP32 reboot? (Reboot cause data loss for graph module).
