generating secure ARGON2ID passwords

I'm using dovecot on a Debian buster system.

with Argon2ID password scheme, it's only possible to configure the
parameters used for it via the generic -r option to "doveadm pw".

A higher -r will increase time and memory comsumption.
But on my dual core VM it always uses p=1.
So it seems the needed threads can only be changed on compile time?

Will there be in future a way to explicitly specify memory, time and
threads needed for Argon2ID?
