I really would suggest looking at whether the particular feature you want are in CDH6.3.3. We do backport a lot of features. E.g the GPU scheduling features for YARN for Hadoop 3.1 were included in CDH 6.2 https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_cdh_620_new_features.html#hadoop_new_620.   If the question is whether you can run a non-CDH version of Hadoop, and still be running CDH, then the answer is no.
