Disabling padding in OpenSSL version 3

Question

im trying to write a program that disable padding when it encrypts a message in C language. I figured out, by reading the documentation, that the correct function to use is EVP_CIPHER_CTX_set_padding(). I used it but the program still doesn't work. Because If I compile it but commenting the function EVP_CIPHER_CTX_set_padding, the ciphertext remains the same... Can you help me?

#include <stdio.h>
#include <string.h>

#include <openssl/evp.h>


#define ENCRYPT 1
#define DECRYPT 0

int main()
{
    

    unsigned char key[] = "0123456789ABCDEF";
    unsigned char iv[]  = "1111111111111111";

    EVP_CIPHER_CTX *ctx = EVP_CIPHER_CTX_new();
    if (ctx == NULL) {
            printf("Error creating cipher context.\n");
            exit(EXIT_FAILURE);
        }

    if (EVP_CipherInit_ex(ctx, EVP_aes_128_cbc(), NULL, key, iv, ENCRYPT) != 1) {
        printf("Error initializing cipher.\n");
        exit(EXIT_FAILURE);
    }

    if(EVP_CIPHER_CTX_set_padding(ctx, 0)!=1){//disabling padding
        printf("Error disabling padding.\n");
        exit(EXIT_FAILURE);
    
    }


    unsigned char plaintext[] = "This is the plaintext to encrypt."; //len 33
    unsigned char ciphertext[48];

    int update_len, final_len;
    int ciphertext_len=0;

    EVP_CipherUpdate(ctx,ciphertext,&update_len,plaintext,strlen(plaintext));
    ciphertext_len+=update_len;
    printf("update size: %d\n",ciphertext_len);

    EVP_CipherFinal_ex(ctx,ciphertext+ciphertext_len,&final_len);
    ciphertext_len+=final_len;

    EVP_CIPHER_CTX_free(ctx);

    printf("Ciphertext lenght = %d\n", ciphertext_len);

    printf("The content inside ciphertext{");
    for(int i = 0; i < ciphertext_len; i++){
        if(i==ciphertext_len-1)
            printf("%02x", ciphertext[i]);
        else
            printf("%02x-", ciphertext[i]);
    }
    printf("}");
    printf("\n");

    return 0;
}
