pcbnew: Cannot place VIA on pad, "VIA location violates DRC"

Description

Cannot place VIA on top of the pad, I don't know how to turn of this obstacle.

5507X

Steps to reproduce

1. Try to put VIA on top of pad;
2. Get error "VIA location violates DRC";
3. Go to Board setup -> "Violation severities" and "Constrains" -> Search for some setting, disabling VIA on pad;
4. I didn't find anything related (not looked very carefully..);

Expected behavior:

• Via is placed on pad in step 2, VIAs net name is automatically set to PAD net name.

Or at least:

• Steps to turn off this obstacle should be provided in step 2.

My preferred way of placing VIAs was:

1. Place via on top of two pads (start and end pads);
2. Move vias to final destinations;
3. Route "start pad" to 1st via -> 1st via to 2nd via -> 2nd via to end pad;

It reminds me some report in gitlab, I am pretty sure it was allowed to place via on pad before..
