The downloads section used to have older OS's that you could download and manually install on devices. We have numerous testing devices that we try to update on a regular basis to a specific version of iOS for testing OS/Device specifically. Is there a way to download specific iOS versions by device or is that option no longer available?

Hello. Downgrades on iOS devices are not supported.
Apple uses a signing system for iOS updates. This means that you can only install whichever version of iOS is currently "signed." For most devices, this version is the latest iOS release that can run on the device in question. As older versions of iOS are not signed, this means you cannot install them even if you have the .ipsw file downloaded.

Not trying to downgrade, these test devices are running older OS's and we want to upgrade to a newer but not current OS.

You cannot selectively update to intermediate versions of iOS. Only the most current version of iOS, compatible with your iPad model, is available as an update.
Similarly, when restoring to Factory Settings, the restore process will always (re)install the most recent version of iOS that is compatible with the device.
Thanks for clarifying. That still would not be possible as the older not-current iOS versions would not be signed by Apple. You will only be able to update to a signed version of iOS on the devices in question.
This is a question to post in the developers forum, not here. Other paid account developers will be your best resource for issues about testing on older versions.
XCode has older iOS version simulators for paid developers to use.
