Sure Please find the code sample below--
  
trigger childTrigger on ChildObject(after update){
Set<Id> oppIdSet = new Set<Id>();      
for (childObject c:trigger.new){
             if(c.firstfield != null && csecondField != null){
                  oppIdSet.add(c.Opportunity__c);      
             }
      }
List<Opportunity> oppListToUpdate = new List<Opportunity>();
for(Opportunity opp: [Select id,FieldToUpdate from Opportunity where Id in:oppIdSet]){
          opp.fieldToUpdate = Value You want to Update;
          oppListToUpdate.add(opp);
}
Update oppListToUpdate;
}

Use this code replace your field names and condition you want to test and then try. Let me know if you have any queries.

Please mark this answer as best answer if it solves your query

You can use process builder as well, by putting the check if condition met the criteria(two fields of custom object met the condition) then update related opportunity field to true.
