How do I pass data to shaders in SDL3 with the GPU API

I’m trying to use one of RetroArch’s shaders in my project, but I’m not sure how to pass data to the layout(push_constant) uniform Push. How can I pass data to it? Does SDL even support these push constants?

Here’s the shader I’m trying to use:

#version 450

layout(push_constant) uniform Push
{
	vec4 SourceSize;
	vec4 OriginalSize;
	vec4 OutputSize;
	uint FrameCount;
} params;

layout(std140, set = 1, binding = 0) uniform UBO
{
	mat4 MVP;
} global;

#pragma stage vertex
layout(location = 0) in vec4 Position;
layout(location = 1) in vec2 TexCoord;
layout(location = 0) out vec2 vTexCoord;

void main()
{
   gl_Position = global.MVP * Position;
   vTexCoord = TexCoord;
}

#pragma stage fragment
layout(location = 0) in vec2 vTexCoord;
layout(location = 0) out vec4 FragColor;
layout(set = 2, binding = 0) uniform sampler2D Source;

void main()
{
   FragColor = vec4(texture(Source, vTexCoord).rgb, 1.0);
}
