You are attempting to get a distribution from 2014 to work with hardware from 2022. CentOS 7 stopped adding new hardware suuport around 2019 so your chances of making this work are slim.

In addition, and an even bigger problem, CentOS 7 only has 9 months of life left before it dies so if you do somehow manage to make this work, in less than a year you will be doing it all again with a newer distro. Why not skip the intervening period and go straight for "install a newer distro".
The future appears to be RHEL or Debian. I think I'm going Debian.

Is there a possibility if we install an extra ethernet card at pcie slot and when we reformat the sytem with the centOS 7 minimal it detects the hardware and works normal (without anything to do with drivers) whose driver is already in that OS

If yes

Can you share me the model and name of the ethernet card

Sure, you can install some supported network card and get it working. I'd suggest that you look at cards that have been around for a while as the same restrictions will apply - too new and the drivers in CentOS 7 will not support it. I've had success with Intel e1000e based cards but I have servers with Broadcom 5719/5720 cards - pick something that existed prior to 2019 and you stand a good chance.

That still will not help you in June 2024 when CentOS 7 dies though. At that point you will need to be doing it all again and I would question if it is worth the effort for such a short time period. Better to put effort into installing something with more of a future - I've skipped RHEL8 and its clones and gone straight to RHEL9 and the rebuilds of that: Rocky, Alma, OEL.

planning to go for

Intel Gigabit PCI-E Network Adapter EXPI9301CTBLK

or

I350-T4V2

or

Intel® Ethernet Server Adapter I210 Series

Which one would you prefer so that the above scenario works without any issue ...

As a temporary solution, you may want to try installing a newer kernel such as kernel-lt or kernel-ml for RHEL/CentOS 7 from ELRepo.

lspci -nn
gives "best" details about hardware even when it is not supported. (The unknown devices do show up with it.)
Particularly, the device ID (looks like [8086:15bb] -- the 15bb is I219-LM) is useful.

One can run the lspci with the install media even without installation of the system.


I've seen notes -- also from Windows users -- that the latest Intel network chips may have issues.
In other words, lack of drivers may not be the only roadblock.

Ironically, the older generation of Intel chips were very good.
