How much memory is available in the 3rd Party Data Store?
Intel® AMT 1.0 systems have 96k of NVRAM. All computers with Intel® AMT 2.0 and beyond have 192k of NVRAM. This said, vendors can probably change this and it’s generally accepted that any single application should not use more than 48k of it so that several applications can share this space. You could also try to use some type of compression when placing data into the 3rd Party Data Store (3PDS) so that this space can be most efficiently.
