You're very welcome.
There are operating system limits and hardware limits.
Theoretically, according to the chipset, the PC should support 2 x 16 GB of memory, and many times the crucial website indicates more memory is supported than the HP service manual does.
When they are both in agreement, it is dubious that 2 x 16 GB would be supported, and the only way to know for sure, would be to try a 16 GB chip and see.
I have no right to gamble with your money, so that would be a decision you would have to make if you wanted to experiment or not.
