Is it possible to hide Captivate Scorm Module results in the LMS system

Yes it is possible to hide the Quiz Results slide in Captivate by deselecting the option in Quiz Settings to Show Score at the End of the Quiz (shown below).

This same setting about the visibility of the Quiz Results slide is shown on the Publish dialog as shown below.  It's not a different setting at all.

But this only refers to hiding the Quiz Results slide in the Captivate module.  It does not mean the SCORM scoring results are not still sent to the LMS.  Whether the LMS shows the scores or not is up to the LMS.  Under the SCORM standard, a valid SCO must report scoring data.

Additionally, since you indicated that you still want the participant to have the option of retaking the quiz again (if they failed to achieve a passing score) then you cannot hide the Quiz Results slide because that is the only slide on which you can have a Retake Quiz button that allows the participant to reattempt the quiz during the same session.

Another way to hide the quiz results from the participant is to still show the Quiz Results slide but deselect the checkboxes that determine which of the quiz details are shown on the slide (see below).

This will still allow the Quiz Result slide to be published with the project but just not show scoring details.

There is no default option in Captivate to publish a valid SCORM but prevent SCORM scoring data from being sent to the LMS. Captivate leaves what the LMS does up to the designers of the LMS.  It obeys the directions of the SCORM standard quite strictly.  But the same cannot be said for all LMSs.  It's also quite common for LMS vendors to blame an issue on Captivate when the problem is really some bug or limitation of their own LMS.

One of the main reasons why a LMS is used, is to transmit scores. Strange answer from the LMS people.

Ask them if their LMS is capable of accepting packages whcih are no SCOs? Some LMSs have that feature, but not all. If that is possible, take out the Reporting from Quiz Preferences and publish as simple HTML5 output. Whether you need to zip it, depends also on the LMS. Example: Blackboard LMS supports such packages, but they need to be zipped and on upload you'll instruct the LMS to unzip and launch from the index.html file.

It their LMS doesn't support non-SCO packages, here is a possibility: I have described a worfklow, where the real score is replaced at the end by either 0% or 100%, depending on either Failure or Success. In that case the learner will not see the real score. Of course you'll need to hide the score slide in the course as well. You cannot delete it because it has its functionality even when being hidden.
