Cert deployment policy Ubuntu 18.04

Hi,

I use certificate scripts/policies to deploy certificates to various Chromium-based browsers.  The following locations are valid and usable for Ubuntu 18.04 with various Chromium-based browsers:

• ~/.pki/nssdb
• ~/snap/chromium/current/.pki/nssdb
• ~/snap/opera/current/.pki/nssdb
• ~/snap/opera-beta/current/.pki/nssdb

... however, I can't find the location to deploy certificate policies to Edge for Linux.  How would I deploy a certificate to Edge for Linux?
