just sequester them in a closed-borders area and forcibly miscegenate them for many generations
you can speed the process by sequencing their DNA and identifying any chromosomes which have markers of the target ethnicity, and match them with mates specifically selected based on possession of chromosomes which might be inherited in their stead
furthermore you could mandate artificial insemination and preliminary genetic sequencing to ensure that all implanted embryos have the minimum number of the target ethnicity's markers
after a number of generations these target ethnicity genes will be completely removed from the sequestered population. At this point they may be safely reintegrated with the broader society
