Disabling parent link

Hello
My site is quite complicated.
Let’s say that structure looks like that(all items are pages):

Home
Zabiegi
– Laryngologia
— Nos
— Zabieg 1
— Zabieg 2
— Zatoki
— Zabieg 3
— Zabieg 4
– Ortopiedia
…
Poradnie
…

Now when I’m in Zabiegi->Laryngologia->Nos->Zabieg 1 all items are link. Is it possible to turn off link for first page – Zabiegi ??

Regards.
Michal
