DFU over BLE + BLE peripherals

Hi. I am trying to build a project with the DFU over BLE on nRF52810. If I only add BLE and DFU modules to prj.conf, FLASH region gets overflowed by 60 KB. I know that this IC has only 192 KB of FLASH and 24 KB of RAM.
Building this project for nRF52832, I can see that the project with minimal configurations uses 133 304 B of FLASH and 24 722 of SRAM, which as to me means that this controller can not be used for this purpose.
However, I would like to know if there is any way to make this work for nRF52810. Maybe i can somehow change the partition scheme of the flash memory region or turn this DFU into a single bank?

Hope this Memory footprint optimization documentation can help. For the single bank, you could do serial dfu within the bootloader itself via UART and USB. Otherwise, it has to be "dual banked". That means the BLE DFU cannot support single bank, unfortunately.
