I see.

No, you don't need to solder them, just make sure that the device is running at 3V and that vREF from the debugger is connected to VDD.

I have made a prototype on a GP board. I am referring https://infocenter.nordicsemi.com/topic/ug_nrf52840_dongle/UG/nrf52840_Dongle/hw_power_ext_reg_source.html.

I am powering nRF52840 using CR2450 battery which is 3V 650mAh

Hi,

Where did you read that you had to cut SB1 and SB2 to use the SWD interface?

It means I need to revert the changes I made to SB1 and SB2 and restore it to USB mode. right?

Hi,

You must set REGOUT0 to 3V0, since the nRF52832 only supports debugging targets at 3V0. You can damage the board, If you don't set REGOUT0 on the dongle before trying to program it from the DK.

See this.

You can use nrf52832 dk, but you have to be clever when connecting it.

The "debug out" connector has a detector pin that is used to switch onto the external target . GND and VCC have to be connected, too.
