How to open lod clamp specified in shader in glsl?

Question

amd instruction set spec said:

IMAGE_SAMPLE_D_CL_O SAMPLE_O, with LOD clamp specified in shader, with user derivatives.
IMAGE_SAMPLE_D_CL sample texture map, with LOD clamp specified in shader, with user derivatives.
IMAGE_SAMPLE_D sample texture map, with user derivatives
IMAGE_SAMPLE_CL sample texture map, with LOD clamp specified in shader.

in vulkan, i use textureGrad in glsl. Running on radeon, i got a image_sample_d in asm

How to get image_sapmle_d_cl in vulkan or opengl?

In other words， how to open LOD clamp specified in shader, as the spec said.

I'm not sure if it's supported by AMD, but there is ARB_sparse_texture_clamp which adds textureGradClampARB in addition to the sparse samplers it adds. — vandench
