You can exclude single modules from autoloading via modules.conf.

But while asterisk is running does the memory usage increase unbounded
till filling all available memory or does it stabilize at some point?

Asterisk is relatively memory hungry, especially with all modules
enabled. It also caches and logs various information in RAM, even doing
"nothing" it will cache and log that "nothing" activity. If memory does
stabilize after some point it's not really a leak but it's standard
memory usage. To reduce it you should disable all unused modules.

I'm not able to give you a correct indication, but if the memory usage
is not increasing indefinitely but is stabilizing I'd say it's not
really a leak.
