[HCoop-Help] Any way to configure mod_headers through domtool?

[Kenneth Pronovici]

I was hoping to opt my sites out of Google's FLoC network [1] by
adding a special header:

<IfModule mod_headers.c>
   Header always set Permissions-Policy: interest-cohort=()
</IfModule>

Is there a way to accomplish this with domtool?  I dug through the
documentation, and I don't think so.  I'm just looking for a
double-check, in case I've overlooked something.

Thanks,

KEN
