There are two options to achieve this depending on your use case.
1. Block access to the editing form.
In this case, the user cannot open the form. You can set a condition on what Airtable record is accessible depending on the values in an Airtable field. You can find this option on:
Form Settings
Disable Editing/Creating Records section
Turn on Allow users to see/edit existing records toggle
Turn on Only allow users to see/edit existing records if conditions are met toggle
Add Condition(s)
2. Prevent saving the form
This feature allows you to access the editing form but restrict submitting the form conditionally based on a rule. You can come up with your own conditions. For example, users can't edit the form when it “expires”. You can set any conditions that will prevent the saving of the form when these rules are not met.

You can find the option in the Advanced section under Disable Form. There are multiple options. You can disable the form based on:
1. Formula
When users try to access the form, they'd see a dynamic error message instead.
2. View
You can configure a custom view filter.
⚠️ Please note that no formula can be calculated on miniExtensions Form itself without creating a record in Airtable first. When creating new records, you can't disable a form before the initial submission. The way it'd work is by allowing all submissions and then you'd filter out the invalid ones on your end.
