Is it possible to update the SoftDevice S112 on nRF52810 using in-place model through UART

Yes, that's correct as far as I know.

Thanks Hakon!

Looking at the referenced example and DFU process for an application in single-bank mode, am I right (on a very high-level) it is something along the lines of:

Creating a similar mechanism to NRF_DFU_SINGLE_BANK_APP_UPDATES for Softdevice:

In nrf_dfu_utils let nrf_dfu_cache_prepare clear and return the SoftDevice location
Make sure in-place SoftDevice is validated (postvalidate_sd_bl)
Skip writing of SoftDevice after validation, since it is already in-place

Yes, I think it should be possible. It should work with the secure_bootloader_uart_mbr_pca10040e example.
