🚸 Reduce CTC A13 build size

[thisiskeithb]

Description

While running the build_all_examples script, this config would not build because it was too large:

Error: The program size (127000 bytes) is greater than maximum allowed (126976 bytes)
*** [checkprogsize] Explicit exit, status 1

Disabling some features brings the build size down.

Benefits

Config now builds.
