Dust transaction created in fundrawtransaction, change_address

I use "fundrawtransaction" rpc to make a transaction and
set "change_address" in params of fundrawtransaction rpc for receiving changes.
However, if changes are too small, then the transaction is rejected to be broadcasted because this utxo is perceived as "dust".

In bitcoin core after v15.0 there is discardfee option in launching node for not making those change address. However, bitcoin cash doesn't have that one yet.

Could you give me how to avoid my situation for broadcasting my transaction?
