If it's the same BIOS as the Samsung Series 3, then yes but it's tricky to find the option in the BIOS.
Google picked up this link when I was looking.. a blog mentioning the aptio bios and that kind of laptop! The blogger's post helped somewhat but 2 comments in particular helped more. The blogger's post mentions some stuff and a comment mentions about a part of the BIOS that says BBS priorities
And in case that doesn't quite cut it, another poster(me), had some luck, solved it and commented with a solution regarding his Series 3, which takes what the blogger wrote + a comment about BBS priorities, and solved it and explained-
And this is essentially the answer.

Aptio bios has hardly any options and
doesn’t show much. A very poor BIOS generally.
I have a samsung NP350
I couldn’t see any option to boot from USB. I updated the BIOS. still
nope. I disabled fast BIOS saved restarted, but no new USB option
appears under “boot override” or anywhere – it seemed.
A normal/decent BIOS e.g. even on a cheap Dell, besides showing far
more in the BIOS, often has an option where a function key offers a
boot menu.
But I tried all the function keys and the only one is F2 to go into
the BIOS.
In the end, I saw that Indeed one had to set advanced.. fast bios
mode..to disabled, and restart. But then my USB stick was under
Boot….Boot device priority….. then it said CD/DVD drive BBS priorities
Hard drive BBS priorities Choose Hard drive priorities Then I saw my
USB key listed.
So, it was within 3 layers!
That which is quoted directly above, has solved it for many people, perhaps for anybody. Hopefully samsung tech support will take note 'cos it had stumped them.
So the comment points out that it's through 3 layers with titles including the term "BBS priorities". the original poster said that the option is called "boot override".
BTW Another user says this of the series 5 aptio bios.
secure boot method option where I could switch from UEFI to CMS
(whatever this CMS means). That did the trick on my NP550P5C and the
USB boot option came alive.
