Put this into /etc/gcrypt/random.conf

--8<---------------cut here---------------start------------->8---
# Options for the random generator

# If you don't want the Jitter based thing you may disable it,

# Only use /dev/urandom
--8<---------------cut here---------------end--------------->8---

That is in general okay because on modern kernels we anyway use the
getrandom call and thus we are eben safe at boot time.
