I edited /etc/ImageMagick-6/policy.xml without success, here is the log of
the first file to convert, extracted from lyx-2.3.7dev -dbg graphics
Can show the current content of that config?
File attached. This is the original bullseye file in which I changed lines 93,
96, 97.
How can I display the conversion process from svgz to pdf6 itself?
You need to enable "files" debug level.
This not very informative, in fact I would like to see the conversion command to
be able to test it from the console.

Configure ImageMagick policies.
Domains include system, delegate, coder, filter, path, or resource.
Rights include none, read, write, execute and all. Use | to combine them,
for example: "read | write" to permit read from, or write to, a path.
Use a glob expression as a pattern.
Suppose we do not want users to process MPEG video images:
<policy domain="delegate" rights="none" pattern="mpeg:decode" />
Here we do not want users reading images from HTTP:
<policy domain="coder" rights="none" pattern="HTTP" />
The /repository file system is restricted to read only. We use a glob
expression to match all paths that start with /repository:
<policy domain="path" rights="read" pattern="/repository/*" />
Lets prevent users from executing any image filters:
<policy domain="filter" rights="none" pattern="*" />
Any large image is cached to disk rather than memory:
<policy domain="resource" name="area" value="1GP"/>
Use the default system font unless overwridden by the application:
<policy domain="system" name="font" value="/usr/share/fonts/favorite.ttf"/>
Define arguments for the memory, map, area, width, height and disk resources
with SI prefixes (.e.g 100MB). In addition, resource policies are maximums
for each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
exceeds policy maximum so memory limit is 1GB).
Rules are processed in order. Here we want to restrict ImageMagick to only
read or write a small subset of proven web-safe image types:
<policy domain="delegate" rights="none" pattern="*" />
<policy domain="filter" rights="none" pattern="*" />
<policy domain="coder" rights="none" pattern="*" />
<policy domain="coder" rights="read|write" pattern="{GIF,JPEG,PNG,WEBP}" />
