Starting at the beginning, while acknowledging that you may have tried some of this already...
An iPad will be disabled or indicate that it is unavailable if an incorrect Passcode is entered too many times.
A forgotten or unknown iPhone/iPad passcode cannot be recovered - and neither can it be reset or modified from another device. If you see a waiting period you can wait and try again to input the correct Passcode; otherwise, the iPad must be restored.

iPadOS 17 or later with a forgotten Passcode
If you have changed your passcode in iOS/iPadOS 17 and later - and have since forgotten the new Passcode - you may be able to recover access using your previous Passcode. Passcode Reset gives you 72 hours to use your old Passcode to access your device; when you access your device in this way, you must change your passcode again immediately:

If you cannot use the new Passcode Reset feature, you must use another method.

You will be able to restore data from a pre-existing iCloud backup without the use of a computer, but will require a PC/Mac to restore data from an iTunes backup.
iPadOS 15.1 and earlier - and all devices that are Disabled
If your iPhone/iPad indicates that it is disabled/unavailable/locked-out, or you have forgotten your iPad passcode, you have no alternative other than to follow this process:

You’ll need access to either a Windows PC (with iTunes for Windows installed - or for Windows 10/11, the more recent Apple Device App) or a Mac computer (with iTunes or Finder - as appropriate for the installed version of macOS).

Use of a PC or Mac is unavoidable. If you don’t have access to a suitable computer of your own, that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store will be delighted to assist:

Activation Lock
Here are the Apple support pages that outline the Activation Lock - and the only mechanisms by which it can be satisfied:

As you will discover, unless you are the owner of the Apple Account (previously known as an AppleID) that was last used to activate the device, you’ll not be able to defeat or bypass the Activation Lock. With documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple may be prepared to assist - otherwise they and nobody here will be able to help you.
If you have the necessary documentation, Apple have introduced a portal though which you may be able to request release of an Activation Lock:

Apple Account (AppleID)
You may also need your Apple Account (AppleID) and associated password. If these have also been forgotten, they can be recovered here:
https://iforgot.apple.com
To recover your credentials, you’ll need access to one of the following:
- Your primary email address mailbox that corresponds with your AppleID
- Any of the secondary/recovery email addresses that should be configured for your AppleID account
- Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID
