Acer Aspire 7 A715-75G-71RD memory and storage capacity

I'm looking to upgrade my old Aspire and am looking at the Aspire 7 A715-75G-71RD model available in Canada.

On the Aspire 7 series page (https://www.acer.com/ac/en/CA/content/series/aspire7) it states: 
"A max of 1TB M.2 PCIe SSD and up to 32GB DDR4 (SO-DIMM) RAM serves your workload, delivering effective power and plenty of storage."

But on the available models the A715-75G-71RD (https://www.acer.com/ac/en/CA/content/model/NH.Q99AA.001) and the AMD alternative both have:
Standard memory = 16GB; Number of Total Memory Slots = 2
Solid State Drive Configuration = 1 x 512GB; Total Solid State Drive Capacity = 512 GB

So my questions are:

1. for RAM, is the 16GB standard memory a single DIMM, leaving a second DIMM where I can add 16GB additional?

2. To get to 1TB storage, is there an additional SSD/M2 slot available to add a second 512GB drive?  Or is the only way to get to 1TB to remove and replace the standard drive that comes with the laptop?

Thanks for any info you can share!

The A715-75G has the following specs that comes from Acer OEM as per its service manual:

1. The memory specs and combinations are as follows:

2. The hard drive specs are as follows; M.2 Interface Number supported is 1 at PCIe Gen3x4 and Fast Data Transfer Rate (Mbits/sec, max) of 1800MB/S  but and within windows the GPT/UEFI and MBR/Legacy formatting hard drive rules apply which is, MBR/Legacy formatting only supports up to 2TB and the GPT/UEFI formatting applies over 2TB capacity drives.

Types of M.2 SSD's fitted by Acer for the 715-75G but higher capcity M.2’s can be fitted (read the MBR and GPT formatting rules in windows) as in GPT/UEFI format you can fit a higer capacity drive than 2TB.
