The question about serialization is up to the consumer of the

can request that the ENQ on the dataset be held to keep

This still doesn't answer the question. Does Zowe obtain the
ENQ, or is it up to the user whether the ENQ is acquired?
It would appear that the answer to your question is here:
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.izua700/IZUHPINFO_API_PutWriteDataSet.htm
Under "Custom headers":
X-IBM-Obtain-ENQ
This header is optional; set it to one of the following values to
request that a system ENQ be obtained and held after the completion of
this request. If not specified, then no ENQs will be held after the
completion of this request.
EXCL
a SYSDSN/Exclusive ENQ will be held on the data set
SHRW
a SYSDSN/SHR ENQ will be held on the data set, and a
SPFEDIT/EXCL ENQ will be held on the data set, including the member name
if this is a request for a PDS member.
A successful response will include an X-IBM-Session-Ref response
header that can be added as a request header to subsequent requests to
specify affinity to the TSO address space holding this ENQ.
In other words, "plays well with the other children, iff requested to do
so."
