i don't because before them there were Beakers

if steppe in nuragics is 3% ex. then modern Sardinians from the coast with 9-10% steppe have a "lot" of ancestry from the Romans and other medieval colonists, somenthing like 20-30%

Sardinia was conquered by Vandals at some point wich were accompanied by Alans, a steppic tribe, it could have played a role.

A conquering horde passing through rarely has much impact. Look at the Hungarians. Even the Langobards didn't have a huge impact, and they were a folk migration.
there were some Vandal settlement on the island, for example a guy named Walderich, a landowner, asked to the Pope to return in Sardinia after the Byzantine conquest
I don't know if the few R1a there match with that of the Vandals, in any case at best their autosomal contribuition must be 1-2%
Also probably the Byzantine enrolled Lombard soldiers to stay on the island

If the Barbagia population has little if any Bronze Age steppes, it is not only the closest population to pre-IE Southern Europe but also among the last population in the Mediterranean basin to have been "spared from" these newcomers as even neighbouring Berbers as well as Levantines have minor steppes ancestry.
The insular situation and the terrain seem to be again at play in isolating Sardinians from migrations despite being in a rather central location.
Both Maritime and Central EuropeanI don't really know the history of Sardinia, but were the Beakers there related to the Mediterranean type or the Corded type? That would make a big difference.
