CRM 2016 Online: Is it possible to set Logical Operator OR between 2 Linked Entities

I have a scenario where I need to set Logical operator OR between 2 Linked Entities. Is it possible to set OR operator between 2 linked entities as shown in the below sample select query

select systemuserid from systemuser

where idisabled=0 AND(LinkedEntity[0] OR LinkedEntity[1])

In the below highlighted linked entities default it is taking AND operator, can any one help how to setup OR operator between these.

Below is the Actual Query Expression that I am using, it is working; however it is using AND operator default need to change OR.

QueryExpression userquery = new QueryExpression("systemuser");
            userquery.NoLock = true;
            userquery.Distinct = true;
            userquery.ColumnSet = new ColumnSet("systemuserid", "fullname");
            userquery.Criteria.AddCondition("isdisabled", ConditionOperator.Equal, false);

            LinkEntity elink = new LinkEntity("systemuser", "new_employee", "new_employee", "new_employeeid", JoinOperator.Inner);
            userquery.LinkEntities.Add(elink);

                LinkEntity culink = new LinkEntity("systemuser", "connection", "systemuserid", "record2id", JoinOperator.Inner);
                userquery.LinkEntities.Add(culink);

            LinkEntity celink = new LinkEntity("new_employee", "connection", "new_employeeid", "record2id", JoinOperator.Inner);
            elink.LinkEntities.Add(celink);

            LinkEntity crlink = new LinkEntity("connection", "connectionrole", "record2roleid", "connectionroleid", JoinOperator.Inner);
            crlink.LinkCriteria.Conditions.Add(new ConditionExpression("category", ConditionOperator.Equal, 206490001));
            celink.LinkEntities.Add(crlink);

                culink.LinkEntities.Add(crlink);

            celink.LinkCriteria.AddFilter(LogicalOperator.And);

            LinkEntity olink = new LinkEntity("connection", "opportunity", "record1id", "opportunityid", JoinOperator.Inner);
            olink.LinkCriteria.Conditions.Add(new ConditionExpression("opportunityid", ConditionOperator.Equal, context.PrimaryEntityId));
            celink.LinkEntities.Add(olink);

                culink.LinkEntities.Add(olink);

            var FinalResult = ImperService.RetrieveMultiple(userquery);
