Which bootloader and NCP firmware are used for EFR32MG13 adapters like Tuya TYZS13 module and Elelabs ELR023 or ELU013?

TYZS13 Module Datasheet says that it used EFR32MG13P732F512GM48 (i.e. EFR32MG13P) with 512 kB Flash Storage.

Is this the same EFR32MG13P SoC that Elelabs Zigbee USB Adapter ELU013 and Elelabs Zigbee Raspberry Pi Shield ELR023 uses?

Use case

Among other products, Tuya TYZS13 module is used in Tuya T6E Android-based panels which have now been hacked by blakadder to run Zigbee2MQTT directly but that first require you to reflash the Zigbee adapter:

blakadder has also hacked ITead's Sonoff NSPanel Pro (which looks to be a rebranded Tuya T6E) the same way by to run Zigbee2MQTT by getting the ADB access that is needed:

The tuya module is using one normal NCP bootloader and can rebooting by software command to it (we have prof of concept posted by user) and if tuya have putting boot pin is not known but is likely then its recommended in most tuya Zigbe NCP dev papers.
