No.
All Apple iOS/iPadOS devices havd a fixed amount of internal data storage that can never be expanded.
If you need a larger capacity Apple iOS/iPadOS device, you need to purchase one with a much larger data storage capacity.
If you own a low storage, 16 GBs device, there is little to nothing to be done.
After a full installation of more recent iOS/iPadOS versions, tbse devices are left with little usable internal data storage space.
If you own a 32 GBs internal data storage device, you should better manage the internal storage you have by backing up the data inside of this device to Apple iCloud and/or other online/offsite data storage backup services, like Google Drive/Docs/Photos, BOX, DropBox, Amazon Cloud services and/or other similar online data storage services and/or to full Mac, using the Finder app, or an older Mac or Windows PC, using the iTunes application.
Then delete stuff off of your iPad that you do use or access everyday, to free up internal data storage space.
Delete any installed apps that you no longer use or use infrequently enough that they aren't missed (you can always reinstalled any purchased or free apps at some time later, as you need them).
In addition, uninstall any games that appear to be using a sizable chunk of your iPad's internal storage, as well!
( A disclaimer to the immediate advice above. )
If you own a 7-10-year old iPad, you SHOULD ONLY delete apps that you have ever seldom used or no longer use as there is NO WAY now, from 2020 onward, to retrieve these old apps from the iOS App Store, any longer.
( Third party iOS app developers have permanently removed all of their older, legacy apps from Apple's iOS App Store servers forever!
There are, VIRTUALLY, NO more older, useful, popular, third party apps for over 8-10-year old iOS devices, any longer! )
Then, thin out/delete any music/videos/movies/TV shows/podcasts/screen recordings/photos-images/eBooks/
eMagazine/iBooks/audio books/Documents/PDFs, etc.
If you use a POP email account on your iPad, delete/thin out any old saved emails that maybe saved to your iPad.
To permanently delete photos/images off of your iDevice go into the Photos app and find the Recently Deleted folder/album and permanently delete any photos/images stored in that folder/album.
Also, you can check to see what other stuff is eating up all your valuable data storage space by going into the Settings App,,General Settings Panel, in the right hand column, tap Storage & iCloud usage panel ( in iOS 11 and later, it’s now called iPad Storage ), in the top Storage Panel, tap the Manage Storage panel, wait for a list of apps to generate that will tell you how much space each app is taking up on your iDevice.
Then, for older iPad models with a Home button, do a hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.
ALL iOS/iPadOS devices need to maintain, at the very least, a minimum of between 3-6 GBs of free data storage space, AT ALL TIMES, to insure normal/nominal functionalities/operation and general overall performance of any iOS device running iOS/iPadOS.
Good Luck to You!
