If I want to use a combination vaccine containing HepB, is it acceptable to give a 4-dose schedule of hepatitis B vaccine to infants?

Yes. The use of a 4-dose HepB schedule is acceptable when giving the monovalent HepB vaccine birth dose followed by the use of Pediarix (DTaP-HepB-IPV) or Vaxelis (DTaP-IPV-Hib-HepB). The use of a 4-dose HepB schedule, including schedules with a birth dose, has not increased vaccine reactogenicity and results in higher final antibody titers that should correlate with longer duration of detectable antibody. The federal Vaccines for Children (VFC) program provides up to four doses of HepB for VFC-eligible children. You may still use monovalent HepB in a 3-dose series.
