There is a fix now for Marlin bugfix-2.0.x (new issue #16224).
Problem: When file Configuration_adv.h is edited to enable display module SD-Slot...
#if HAS_SDCARD_CONNECTION
#define SDCARD_CONNECTION LCD
#endif
This configuration enables SD-slot on display module, and disables Onboard SD-slot (except for bootloader on powerup to enable firmware updates).
Since both Display and Onboard SD-slots share the same SD_DETECT_PIN, only one SD-card can be used.
