Hi,
You can go to file skin\frontend\sns_amoda\default\less\content\home.less add style
.sns-slideshow .jssora15l .fa,
.sns-slideshow .jssora15ldn .fa,
.sns-slideshow .jssora15rdn .fa,
.sns-slideshow .jssora15r .fa{display: none !important;}
.sns-slideshow .loading .icon-loading{display: none !important;}
.sns-slideshow .jssora15l, .sns-slideshow .jssora15ldn, .sns-slideshow .jssora15rdn, .sns-slideshow .jssora15r{display: block !important;}
.sns-slideshow .jssorb13{display: block !important;}
.sns-slideshow .jssorb13 > div{display: block !important;}
or you can go to admin sns theme -> advance setting add custom css as above.
with add pagination dots to the sliders you can consult style sns-camen.
