How to remove `is_read_only` attribute from a dashboard in the datadog provider

I have a datadog dashboard which had been assigned is_read_only = true attribute early on. I’m trying to remove this from the dashboard (which would set it to the default value of false), but on trying to apply the new plan, it fails with the error message

error updating dashboard from https://api.datadoghq.com/api/v1/dashboard/hn2-9b4-7x4: 403 Forbidden: {"errors":["This dashboard is read-only"]}

I already know that the is_read_only attribute is deprecated and it’s recommended to use the restricted_roles attribute instead, but as of now I don’t intend on restricting the dashboard at all. How can I make this happen
