Two different OLED displays connected through the same SPI bus lines to the MCU

Is it feasible/safe to connect two separate SPI-based OLED displays to a single ESP32 by sharing the SPI bus lines (SCLK, MOSI, and optionally MISO), while using separate chip select pins for each display?

That depends on the display.Do they have a chip select input?Alternatively, you could use a simple AND gate and 'split' the SPI that way.
