Not directly, no. But you could do this:

SQL> create sequence test_seq;

Sequence created.

SQL> create or replace function get_test_seq return integer is 2 v_seqval integer;
3 begin
4 select test_seq.nextval into v_seqval from dual; 5 return v_seqval;
6 end;
7 /

Function created.

SQL> declare
2 v_test1 integer := get_test_seq;
3 begin
4 dbms_output.put_line(v_test1);
5 end;
  6 /
