in configuration.h //#define SD_CHECK_AND_RETRY ---> #define SD_CHECK_AND_RETRY //#define SDSUPPORT ---> #define SDSUPPORT

in configuration_adv.h

//#define SDCARD_CONNECTION LCD ---> #define SDCARD_CONNECTION ONBOARD

for the moment do not activate in marlin 2.1.1 the ---> //#define POWER_LOSS_RECOVERY no --> #define POWER_LOSS_RECOVERY the motherboard stays in error mode with the flashing blue led. 18 days studying the possible errors of marlin 2.1.1 in MKS-TinyBee that in the end I found the problem in MKS-TinyBee, I have not tried with Marlin 2.1.1 with bug fixes, only with Current Marlin Release. Since MKS-TinyBee has 8M of free memory, I'm activating everything. I still need to test the bed probe, since I don't have the probe.
