Is it possible to stop rebase of a specific wallet in a ERC20 rebase/elastic token?

In my ERC20 token, when rebase happens it increases every wallet's balance. I want to stop some wallet's rebase, So that their balance should remain same. Is it possible to do? Here below is the rebase function

function coreRebase(uint256 supplyDelta) private returns (uint256) {
    uint256 epoch = block.timestamp;

    if (supplyDelta == 0) {
      emit LogRebase(epoch, _totalSupply);
      return _totalSupply;
    }

    if (supplyDelta < 0) {
      _totalSupply = _totalSupply.sub(uint256(-supplyDelta));
    } else {
      _totalSupply = _totalSupply.add(uint256(supplyDelta));
    }

    if (_totalSupply > MAX_SUPPLY) {
      _totalSupply = MAX_SUPPLY;
    }

    _gonsPerFragment = TOTAL_GONS.div(_totalSupply);

    nextRebase = epoch + rebaseFrequency;

    emit LogRebase(epoch, _totalSupply);
    return _totalSupply;
  }

Here is my balanceOf function

function balanceOf(address who) public view override returns (uint256) {
    return _gonBalances[who].div(_gonsPerFragment);
  }
