Disabling FBE will get you what you want, though it seriously reduces the security of the device.
File Based Encryption (FBE) is called "Strong Protection" in the settings. On my tablet, you can disable it in Settings > Security > Other Security Settings > Strong Protection. (My tablet is a Samsung Galaxy running Android 11.) On some other devices it is under Biometrics And Security > Other Security settings.
I'm okay with disabling FBE, because the tablet is for my kids, who don't have much confidential information. But even in my case the tablet has all our Google passwords, because it's almost impossible to use an Android tablet without storing your Google password in a few apps.
(I deserve no credit for this answer, since it just combines information from comments. But I thought it would be nice to put the pieces together for someone who actually wants to change the setting.)
