Contract ERC1155Drop.sol, setClaimConditions() is not override-able. Causing complexity in defining immutable conditions on demand

/// @dev Lets a contract admin set claim conditions.
    function setClaimConditions(
        uint256 _tokenId,
        ClaimCondition calldata _condition,
        bool _resetClaimEligibility
    ) external override {
        if (!_canSetClaimConditions()) {
            revert("Not authorized");
        }

        ClaimCondition memory condition = claimCondition[_tokenId];
        bytes32 targetConditionId = conditionId[_tokenId];

        uint256 supplyClaimedAlready = condition.supplyClaimed;

        if (targetConditionId == bytes32(0) || _resetClaimEligibility) {
            supplyClaimedAlready = 0;
            targetConditionId = keccak256(abi.encodePacked(_dropMsgSender(), block.number, _tokenId));
        }

        if (supplyClaimedAlready > _condition.maxClaimableSupply) {
            revert("max supply claimed");
        }

        ClaimCondition memory updatedCondition = ClaimCondition({
            startTimestamp: _condition.startTimestamp,
            maxClaimableSupply: _condition.maxClaimableSupply,
            supplyClaimed: supplyClaimedAlready,
            quantityLimitPerWallet: _condition.quantityLimitPerWallet,
            merkleRoot: _condition.merkleRoot,
            pricePerToken: _condition.pricePerToken,
            currency: _condition.currency,
            metadata: _condition.metadata
        });

        claimCondition[_tokenId] = updatedCondition;
        conditionId[_tokenId] = targetConditionId;

        emit ClaimConditionUpdated(_tokenId, _condition, _resetClaimEligibility);
    }

This above function should have override ability. Having virtual should be an option incase someone wants to add immutability to some of claim conditions on lazy mint.
Having this option doesn't effect security if people just use the factory contract.
