Hello @Thomas Ingenhorst
Unfortunately you can't install Databricks Simba Spark Driver in my Azure App Service driver when using App Service Windows.
One possibility is to use Windows or Linux Containers on Azure App Service in which you have control over what drivers or custom software to install.
Please check the quick start to run a Windows or Linux Container in App Service:

Example of Linux App Service Container Dockerfile:
# Install Databricks ODBC driver.
RUN apt update && apt install -y unixodbc unixodbc-dev freetds-dev sqsh tdsodbc unzip libsasl2-modules-gssapi-mit
