• Welcome to TeX SX! Not all fonts have bold small caps. Which one do you use? – Bernard Jan 18 '18 at 12:07
• if your font has a bold smallcaps then \textbf{\textsc{Bold Small Caps}} will work, but if there is no such font, latex can not create it from nothing so you will get a warning that a font is being substituted. – David Carlisle Jan 18 '18 at 12:22
• If you fake the small caps, you can combine it with bold. SHown here with italic: tex.stackexchange.com/questions/32942/…. The key to a reasonable fake is different vertical and horizontal scales. – Steven B. Segletes Jan 18 '18 at 13:00

With the fontenc you can get bold small caps, though not for all fonts.
