Steps to reproduce:

1. https://www.zabbix.com/documentation/devel/en/manual/installation/requirements

10.5.00-11.2.X InnoDB engine is required.

The recommended version is 10.5.

We recommend using the MariaDB Connector/C library for building server/proxy.

See also: Possible deadlocks with MariaDB.

Result:
https://mariadb.com/kb/en/mariadb-server-release-dates/:

10.7 -> 10.10 already not supported by MariaDB
10.5 -> support ends in 1 year
10.6 -> support ends in 2 years

Expected:
For LTS 7.0 with 5 year support consider using recent LTS version of a MariaDB database.

Works OOB:

• 10.11.+ (recommended in a requirements)
• 10.6.+ (due to the Enterprise version of MariaDB)

Works with AllowUnsupportedDBVersions:

• 10.5.+

Not able to start even with AllowUnsupportedDBVersions:

• 10.7-10.10
• <10.5

Make base and recommended version: MariaDB 10.11 (such version even provided by recent Debian 12.x), also there is no issue to install it from official MariaDB repository.
