Not supported yet. And, there has been no deadline set or plan in progress towards its completion, yet.

Best said, it will be supported when there is a strong requirement and resources assigned (or there is a community contribution) or as a dependency to other features that may be planned into the roadmap.
That said, there is very experimental initial work of having non-connectable non-scannable advertising implementation that can be tested in the shell application using advx and scanx commands. This may be broken, as I have not tested it for a long time. At present, the implementation may only be there as an inspiration to pick it up and continue the implementation towards a full feature support. Efforts may range upto 6 man months (finger in the air).

When you say " Long range is not supported in advertising", does it mean " Long
range **will never be** supported in advertising" or " Long range is not
supported in advertising **yet**" ?
If this is the later, is there a milestone for this functionnality?

LE Coded PHY
Well, I can compile and run the zephyr samples (e. g. peripheral_hrset which phy (S=8 or S=2) should be used (for advertising and connection).
and central_hr). They are using longe range. I am now wondering how I can
Long range is not supported in advertising (Extended Advertising feature is not
supported), hence long range connection too cannot be established. After
legacy connection is established Bluetooth Host performs a PHY update
procedure to achieve a preferred 2M PHY connection (by default, behaviour if
peer supports 2M). This code is internal in hci_core.c, you may change the
preferred PHY to S8 or S2 instead for experimentation (only). Feel free to revert
back if you face issues.
