In inverse order:
This particular chip '1064' is not listed in the pci.id directory
although the company is.
Will that cause problems for my use?
Binding the driver to the card does not look at all straightforward.
If this is something that
I would need to do - - - - would I be able to get assistance (please)?

Reading in ASMedia Technologies web site.
in ascending order:
1061 - - - 2 ports
1062 - - - Gen 2 x 2 (pcie) - 2 ports
1064 - - - Gen 3 x 1 (pcie) - 4 ports
1164 - - - Gen 3 x 2 (pcie) - 4 ports
1166 - - - Gen 3 x 2 (pcie) - 6 ports

The AHCI driver lists the ASM1062 and also the ASM1062 with the JMB575.
There is no listing for the 1064 or the other two newer chips.
Does this mean that I might have issues using this card?

Greatly appreciating the gentle introduction to the arcane arts of 'under the
hood tinkering' (!!!).

Thank you greatly for your assistance.
