httpd.conf error_page Equivalent

[Daniel Melameth]

In nginx, for one of my servers, I would redirect a 404 by doing the following:

error_page 404 /;

In httpd on 5.7-stable, I'm uncertain how to do this.  I tried the
following, but this appears to only work with 3xx codes:

block return 404 "/"

Assuming this is possible with httpd, how can I redirect a 404?

Thanks.
