This allows enabling TBS for TX queues by adding the
snps,time-based-scheduling property. You should check for support for this
on your particular controller before enabling. Typically, TX queue 0 does
not support TBS.

More a general question: Do i see that correctly that Launch Time does
not work for OF platforms (such as an imx93) at the moment, because the
tbs_en property is not configured? Or why are these patches necessary?

Correct.  You cannot use etf qdisc with "offload" on for OF platforms,
including imx93.
Doing that will end with "return -EINVAL" in tc_setup_etf().

I am working with imx98mp, but there should not be any difference for
imx93.
