No better results trying to use the Ardour ALSA

allows choosing 32 or 64 for period size,
Try ardour/git that allows for non power of two buffers. or more
specifically the ALSA backend explicitly offers millisecond buffer-sizes
for devices that require it e.g. recent HDA Intel via SOF (Sound Open
Firmware).
Also as of yesterday's git, today's nightly.ardour.org build
ARDOUR_ALSA_DEBUG=1024 Ardour6
will first try to use interleaved access and then fall back to
non-interleaved instead of the other way around.

PS. With a HDA Intel card here all I/O is MMAP interleaved. The device
returns an error when trying to configure it with
SND_PCM_ACCESS_MMAP_NONINTERLEAVED.
