Sure we can ... the nv driver is the same on both the Live CD and the
distro. (Same xorg software).  It isn't really blame ... that hardware
is just not on the supported list.  It may be fixed on a future upgrade.

You can probably also use the nvidia option from the live CD as well ...
however I know that does not help you get the distro installed.

You can do the command lvm from the command line {press alt-F2 to get a
command line (after the Welcome to CentOS and prior to going into disk
druid)} to manually setup your LVM prior to entering the manual disk
druid setup ... then assign things to that setup.

We are not going to do major changes to the anaconda or xorg packages
that are not initiated from upstream. I am sorry, but that is just how
it is.  They may support that card later, they do not now.
