Input CSS to the parser:

swc:

            -webkit-mask-composite: source-out;
            mask-composite: subtract;
          }

Input CSS to the transform:

babel:

        .head {
          position: relative;
        }
        .avatar-wrapper {
          width: 40px;
          height: 40px;
          background: #ff6b6b;
          border-radius: 50%;
          mask-image:
            url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><circle r="0.5" cx="0.5" cy="0.5"/></svg>'),
            url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><circle r="%%styled-jsx-placeholder-0%%" cx="%%styled-jsx-placeholder-1%%" cy="0.5"/></svg>');
          mask-size: 100% 100%;
          mask-repeat: no-repeat;
          mask-position: center;
          -webkit-mask-composite: source-out;
          mask-composite: subtract;
        }

Output CSS from transform

babel

.head {
  position: relative; }

.avatar-wrapper {
  width: 40px;
  height: 40px;
  background: #ff6b6b;
  border-radius: 50%;
  mask-image: url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><circle r="0.5" cx="0.5" cy="0.5"/></svg>'), url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><circle r="%%styled-jsx-placeholder-0%%" cx="%%styled-jsx-placeholder-1%%" cy="0.5"/></svg>');
  mask-size: 100% 100%;
  mask-repeat: no-repeat;
  mask-position: center;
  -webkit-mask-composite: source-out;
  mask-composite: subtract; }

With custom babel plugin (sass):

 .head {
  position: relative;
}

.avatar-wrapper {
  width: 40px;
  height: 40px;
  background: #ff6b6b;
  border-radius: 50%;
  mask-image: url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><circle r="0.5" cx="0.5" cy="0.5"/></svg>'), url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><circle r="%%styled-jsx-placeholder-0%%" cx="%%styled-jsx-placeholder-1%%" cy="0.5"/></svg>');
  mask-size: 100% 100%;
  mask-repeat: no-repeat;
  mask-position: center;
  -webkit-mask-composite: source-out;
  mask-composite: subtract;
}

swc:

.head.__jsx-style-dynamic-selector {
	position: relative
}

.avatar-wrapper.__jsx-style-dynamic-selector {
	-webkit-mask-composite: source-out;
