Yes you can using Qlik Sense Enterprise Server, not on the free version of Qlik Sense Cloud. As you have stated, this is a capability known as Section Access and Dynamic Data Reduction. You can read more about it here if you need more info.
I assume you mean for Qlik Sense Cloud, as you posted in this forum. More capabilities are being added as well as subscription based cloud services which will most likely include additional security features.
If you mean Qlik Sense Desktop - no this feature is not available as Qlik Sense Desktop is free for individual business and personal use.
Please let me know how else I can assist.
