Automated Multi-mode charging

Does anyone have any information on connecting Quattro Inverter/Charger, 30A 12v dc-dc Charger and MPPT charger in parallel to charge the same battery bank, from multiple sources without manual switching

I'm not sure about off-brand MPPT chargers, but if you are using a Victron BlueSolar or like-named MPPT charger, those are most definitely intended to work in parallel with a Multiplus/Quattro connected to the same battery bank..

If you are using them in conjunction with a VenusOS product (ColorControl GX, VenusGX, etc), I believe you can set up your system such that there is a maximum amount of net charge current allowed, which the system then automatically limits the charge current coming from the Quattro if there is a lot of incoming solar energy.
