No, because you need to retain the petrol fuel system to start and run on LPG, so you can't just fuel it on LPG alone. if you could, everyone would do that rather than use petrol.

I had a Berlingo van with a factory LPG conversion.  I found it to be very tempremental and eventually gave up & just ran it on petrol.

Modern systems may be more reliable - this was 10 to 12 years ago.

Been there and done that, now just drive a diesel instead. Easier and cheaper to service and no having to hunt around
for an LPG station.

LPG has fallen out of favour.

Years ago it was fairly cost effective to fit conversions to slightly older gas guzzlers as it was cheap to convert larger cars/engines with simple fueling setups.

Modern cars tend to require more expensive conversion parts to cope with their modern fuel injection and ignition systems.

This plus manufacturers who used to offer factory conversions soon started to offer alternatives to petrol/LPG which tended to be cheaper and/or better.
Modern common rail diesels became popular and produced acceptable power, toqure and refinement with good mpg and Hybrids started to be more wide spread and gave diesels and petrol/LPG a run for their money.

Onwers were no longer buying 4 litre plus petrol Range Rovers that were cheap to convert becauce the diesel alternative was abysmaly slow and noisy. The newer diesel alternative was now perhaps better and far cheaper to run than the petrol, even with an LPG conversion.

There are still countries that still widely use and supply LPG or CNG and manufacturers still sell cars capable of running on it.
Places like Australia have tended to hang on to the stuff for a while longer as they produce the gas locally.

I had a petrol/LPG camper van that was an absolute nightmare. I spent over a grand trying to get it to work properly but never succeeded and ended up just running on petrol. Another problem is finding somewhere that still sells LPG for vehicles. My nearest LPG pump was 8 miles away.

 This why "valve oiling" is a priority for ant LPG conversions, although some cars dont require it

Yet on the continent every garage stocks LPG... curious

We have 2 local garages selling it

 I did mean dual-fuel, not gas to the exclusion of petrol
