Hi, you need a programmer that support 1.8V in this case, for instance:

Or you may try to add a bi-directional logic level converter between, though I have not tested this:

can you suggest what kind of programmer 1.8v can I use?

I use now nRF52 Development Kit when I connect external 1.8v to Ref pin on the nRF52 started to program but fail on the some pages. looks like isn't sufficient 1.8v for programming.

Of course you can program it at 1.8v, but you need a 1.8v j-link to talk to it. When you run the nRF at 1.8v the gpio&SWD is also at 1.8 and therefore cannot communicate to 3.3v SWD on j-link.
