Disable NextCloud Text template picker

When creating a new markdown file (using NextCloud Text), a template picker pops up. This offers several templates, of which only ‘blank document’ is useful to me. The picker always opens for the first time with a considerable delay (20 s or more). For an unnecessary feature, this is quite a usability hit.
Is it possible to disable the picker for NextCloud text and just create a blank file by default? i am comfortable digging into the inner working of the code if that is necessary (although a solution that would persist through Docker updates would be elegant).

I am using the NextCloud Hub 10 (31.0.0) Docker image running under Ubuntu (arm64).
