my question was not primarily about how to delete data, but whether it is possible to create a clean installation when creating Pimcore in bitnami hosting.
The Pimcore development documents (https://pimcore.com/docs/5.x/Development_Documentation/Getting_Started/Installation.html) list the following installation options:
Skeleton Package (only for experienced Pimcore developers) ¶
COMPOSER_MEMORY_LIMIT = -1 composer create-project pimcore/skeleton my-project
Basic Demo Package (PHP Templates) ¶
COMPOSER_MEMORY_LIMIT = -1 composer create-project pimcore/demo-basic my-project
Basic Demo Package (Twig Templates) ¶
COMPOSER_MEMORY_LIMIT = -1 composer create-project pimcore/demo-basic-twig my-project
Advanced Demo Package (E-Commerce, PIM, MDM, DAM, ...) ¶
COMPOSER_MEMORY_LIMIT = -1 composer create-project pimcore/demo-ecommerce my-project
As mentioned above, you could give the option to create a Pimcore by 1: create-project pimcore/skeleton my-project.
This could be done as follows: when choosing an bitnami server application would be, for example:
Where Pimcore 6.6.7-0 would be the version under point 1 and Pimcore 6.6.7-0-Demo would be the option under point 2.
Or choose from all installation options from point 1 to point 4, namely:
Pimcore 6.6.7-0-Pimcore developers
Pimcore 6.6.7-0-Demo PHP Templates
Pimcore 6.6.7-0-Demo Twig Templates
Pimcore 6.6.7-0-Demo E-Commerce, PIM, MDM, DAM, .
