Short answer to this is “no”*
Long answer is mostly no but with a work-around, the main reason for the no is we simply set the type-value on the DB schema (for SQL databases) or just set the type-value (without validation) on MongoDB
The query apis basically sanitize this out if you actually tried to modify it as the databases themselves set the values, not Strapi.
The workaround would be to disable time stamps on the model settings (can’t do this through the UI, have to edit the model settings manually) and then add your own datetime field that you can control.
